Star Trek was one of the most popular TV series of the '60s and has turned into one of the biggest, most well-known brands on Earth. After the series' end at its third season came a few different movies, a couple different spin-off shows, and not to mention the reboot movies and new TV show. It may be 50 years and two Kirks later, but Star Trek fans show no signs of letting the show go that easily. Like Star Wars, it has remained a household name and has had at least three generations of fans. Maybe it's due to good writing and loveable characters, or we as a society just really love space! Either way, we're pretty sure Star Trek is here to stay.

One thing that's really hard to not do is make some mistakes. Sure, it's not really acceptable in film & TV, but when the plot, characters, and lore go this deep, it's hard not to make some repeats or go against what the rules were twenty years ago. We have to accept Star Trek is going to have some mistakes as it spans half a century. Seriously, no one working on any of these movies/shows could possibly remember every single scrap of knowledge about the Star Trek universe. That's why in this list we will be discussing the top 25 glaring problems with Star Trek that fans don't know about, or just won't admit. Even though these problems and issues are real we'll be forgiving them entirely as there is so much lore to remember, and we simply love Star Trek.

25 Star Trek: Beyond's Villain

via: bustle.com

While most of us can agree that the Star Trek reboot movies were better then we expected (well, the first one anyway), the third installment of the franchise had some issues. Star Trek: Beyond was released in 2016 and was greatly anticipated by fans.

While the movie was pretty good and the makeup was amazing, one thing just didn't make sense. The main villain of the film, Krall, really has no good reason for being a villain. He kind of just hates the Federation to hate it. As a former captain, maybe he just holds a grudge?

24 How Kirk Became Captain

via:memory-alpha.wikia.com/

In the original series, Kirk was brought in on the second episode, taking over for Captain Christopher Pike. Makes sense, right? Well, the new movies don't really follow that tradition. James T. Kirk is a bad boy who happens to fall nearly onto an older Captain Pike, who offers him a position at the academy.

Two short years later, Kirk becomes Captain of the Enterprise without even graduating, or training properly like everyone else.

His confidence and genius kind of just get him there. Something we found interesting was Chris Pine plays the role of Kirk who's father figure is Chris Pike... we've come full circle here.

23 All Of Khan's Powers

via: inverse.com

According to both versions where Khan shows up (should we still call it a spoiler?) he's this unstoppable, inhuman, extreme species. He's powerful beyond anything a normal human can be, and yet it still seems unrealistic. When Khan shows up in the original series, Kirk has a tough time fighting him but easily wins.

It's the same in the second installation of the reboot movies Star Trek: Into Darkness, Khan is eventually defeated. When you create a character who is supposed to be the most powerful being in the universe, it just doesn't make sense for him to go down so easily.

22 Geordi's Traveling Uniform

via:geektyrant.com

If you're not familiar with Geordi, he is a character in one of the popular Star Trek spin-off shows, Star Trek: The Next Generation. Like we said at the start of this article, there's a lot to remember during one episode of ST, so we understand slip-ups. In an episode of TNG, there's a different reality than normal.

It's like we get to see a different universe, where the Klingon War had never ended. One thing was the Star Fleet uniform. Naturally, everything gets resolved and we go back to normal, but Geordi's uniform was still that of the other universe. A mistake, or did the wrong Geordi come back...?

21 Miles O'Brien Is Talented

via:ds9.trekcore.com

Miles O'Brien is a character that was able to appear on two different Star Trek shows, The Next Generation and Deep Space Nine. He's a main cast member on Deep Space Nine, but a lot of fans think he wasn't meant to be, which is why his character is kind of a mess.

We get moving up in rank is something most officers go through, but Miles has been Ensign, Chief, Lieutenant, Chief of Operations, and a few more titles. He has also had different uniforms he wasn't supposed to be wearing and missed his Insignia a lot. So either Miles is the most scattered person alive, or the writers sloppily threw his character together.

20 Kirk Being Reprimanded

via:brainknowsbetter.com

At the start of Star Trek: Into Darkness Kirk is demoted from being Captain of the Enterprise because he breached protocol. If you hadn't seen the first film, basically every single one of Kirk's decisions as Captain is a breach of protocol.

We're not sure if it was supposed to show Kirk isn't as untouchable as he thinks he is, or everyone in power has amnesia and forgot all the awards they gave him in the last film. Either way, naturally Kirk resumes power a short while later.

19 Stay Away, William Shatner

via:scifi.stackexchange.com

William Shatner already goes down in history as one of the most known actors of all time. He brought one of the most loved characters in pop culture alive, and Shatner's Kirk still holds up as an all-around good guy today. While a lot of fans laugh at some of the terrible acting in the original series, it's loved.

The same is not said for William Shatner's directing. If you didn't realize, he directed Star Trek V: The Final Frontier. Some could go as far as to say this film was more like Shatner's OOC (out of character) fan-fiction. A lot of the film is set in relaxing parks, camping and Kirk is friends with Klingons. In the next film, he hates them again? There's just a lot to unpack here...

18 Klingon Continuity Errors

One thing that's been consistent in the Star Trek lore is how different the Klingons are in each version. We're not sure why since basically everything else has been able to stay the same. Do the writers/makeup just not care that much for Klingons or is it to make them scarier? We're not sure.

From first seeing them in the original series to Next Generation to the most recent Discovery, the Klingon appearance has changed a lot. They started off with smooth foreheads and then out of nowhere their famous forehead bumps were created. Apparently, lazy writing said mutation changed the forehead. We'll just have to leave it at that.

17 Beastie Boys

via:bustle.com

We never thought we'd have to talk about the Beastie Boys in the same conversation as Star Trek, but here we are. In Star Trek: Beyond, Beastie Boys music is played for the crew to listen to and is actually part of the plot.

What makes this weird and a time paradox is, the Beastie Boys song Intergalactic mentions Spock.

This makes no sense in the Star Trek universe as it is hundreds of years after the Beastie Boys existed, so how could they mention Spock? In reality, it's just that they wanted cool music and didn't look deep enough into it to realize. It is really a minor mistake, but from the ST point of view, there's a lot of questions to be brought up once Kirk listens to that song.

16 Spock's Changing Emotions

via:pinterest.com

Spock is the Vulcan everyone loves. Being half Vulcan and half human means Spock can choose whether he wants to feel emotion and live like normal humans, or be devoid of feelings and live solely by logic like normal Vulcans do. From the original series to the new reboot movies, we constantly see Spock do both.

Spock, canonically, has a lot of different girlfriends and is being introduced to the concept of love. Apparently, he finds this difficult and chooses to remain more Vulcan, but then goes and tries to sacrifice himself for his friends a few times. Also, since he's half human, shouldn't he be able to understand emotion anyway?

15 McCoy's Clothing

via:wherenobloghasgonebefore.blogspot.com

This one is more of a filming continuity error than the actual lore of the show, but it was still a pretty obvious mistake that should have been caught. Back in the original series of Star Trek, no one really thought episodes would be watched as much as they are, which is why they probably left this in.

In Season 1 Episode 6, 'Mudd's Women,' we see the crew of the Enterprise being totally blown away by the three beautiful women. Dr. McCoy must have been especially entranced by them as he changes from his uniform to his scrubs in about five seconds.

14 Kirk's Candles

memory-alpha.wikia.com

We don't blame anyone for this mistake as filming with live candles is difficult. The more "takes" it takes and the angles add up to there being uneven candle lengths in different shots. William Shatner is no stranger to this. In Star Trek IV: The Voyage Home, Kirk is having a candlelit dinner with Gillian.

As the camera cuts between the two characters, the candles on the table are different lengths each time. It's supposed to be mere seconds between in the movie, but it must have taken a while to get things right while filming.

13 The Missing Insignias

via:startrek.com

If there's one episode of the original series that's memorable (even though basically all of them are), it's the one with Captain Kirk's villainous double. Other than the fact that the stunt double wasn't Shatner was clearly obvious at times (it was the 60s, they did what they could!), there was another mistake.

The fight scene between William Shatner and himself is one of the most entertaining to this day.

All Starfleet uniforms have insignias on them. Someone in wardrobe must have forgotten to put it back on because throughout the episode Kirk and his twin's shirts are missing them.

12 The Voyager's Reliability

starship.wikia.com

If there's one ship that we would like to be on if we had to, it would definitely be the Voyager. This ship has gone through some traumatic experiences but still managed to come out basically brand new.

During the run of Star Trek: Voyager, it was told that the ship was stranded 75,000 light years away from any source of help, including Starfleet. This doesn't really add up as through the run of the show the Voyager went through some battles, yet the crew was able to maintain it in nearly perfect condition.

11 Picard Is French?

via:syfy.com

We never really considered the different backgrounds of the crew, but Picard's is just so confusing. Instead of the usual American Starfleet Captain, the USS Enterprise-D Captain Jean-Luc Picard is French. That's fair enough, but the actor, Sir Patrick Stewart, has a British accent in the role.

When Picard's family are introduced throughout the show they also have British accents. We can't figure out why they didn't just change his heritage from French. It's alright if the actor couldn't do a French accent, but why leave Picard French?

10 The Uniforms Change

via:theverge.com

We understand that clothes change with the times. The Starfleet uniforms changing between series/films makes sense, style changes in real life too. It just gets confusing when the Starfleet uniforms are inconsistent during the run of one show. The original series showed us three colors, which were generally used in the other series as well, just tweaked a bit.

Then they started just making new uniforms. Voyager also had a lot of changes during its run. Since Star Trek: Discovery was released things have gotten confusing. How do they explain the modern, advanced uniforms when it's set before the original series?

9 Klingons Evolving

memory-alpha.wikia.com

It's just not the appearance of Klingons that keeps changing. While we know that since the original series aired, Klingons have basically gone through a new evolution looks wise. It's also medically that the Klingons have changed.

Why is it just the Klingons? There are so many species in Star Trek.

Klingon blood has evolved too. This could just be a slip as the first time we see Klingon blood is kind of minor, something easy to forget. In Star Trek VI: The Undiscovered, it's shown that Klingon blood is pink. The next time we see one bleed in The Next Generation, it's red. Forgetfulness or a choice? We'll never know.

8 Prime Directive

via:blackgate.com

The Prime Directive is basically the one rule that Starfleet crews have to follow. It's literally just 'leave things alone and finish your mission without interfering. The whole reason Star Trek became a TV series was because Captain Kirk liked to break this rule.

We, as an audience, like when they break it too as it means things get interesting, scary, or heartfelt when it's for a good reason. It seems that Starfleet also doesn't really care about the number one rule of Starfleet, because no one ever seems to be reprimanded for it.

7 Warp 10

memory-alpha.wikia.com

One of the coolest things in Star Trek is when they warp through space. Instead of spending three months moving around like us mortals, the Starfleet crews can warp and basically just get there immediately.

All the awesomeness was kind of doused when warps started to get confusing. In Voyager season two, the Voyager manages to hit 'Warp 10,' which is apparently the fastest they've ever gone. It was contradictory though as there were mentions of higher warp speeds throughout the ST lore. We're not sure what's what anymore.

6 Too Much Stunt Double Stuff

memory-alpha.wikia.com

We mentioned this briefly earlier, but the episode of the original series with Kirk's sinister twin is simultaneously the best and the worst. It's so bad it's good. It was the 60s so we didn't expect much in the way of CGI.

We love the idea and William Shatner's acting, but the execution was a little rough.

You couldn't have The Social Network-level twins back then, but we feel like the stunt man acting with Shatner could have looked a little more like him. Or they could've cut the scenes a little better, it's clearly two different people.
