My problem with the Abrams films is they're stupid and very boring action movies. Most action films nowadays suck, and these movies just blend right in with them. Beyond was one of the most boring films I've seen in a long time, I don't remember most of it in fact. They're all my least favorite of the films. I even enjoy Star Trek 1 more, given it has interesting ideas behind it.
I've rewatched a good deal of all the series, and surprised that my opinions have changed slighty:
TOS
I haven't seen this series in several years, last time was I think five years ago when I binged watched it with my brother on a local LA channel that was airing reruns of it. Now I've seen a good deal on Netflix, and it's pretty good. Sure, trying to make a series like that nowadays would be a disaster, but beyond all its 60s cheesiness and terrible acting, there's some damn good science fiction and characterization here. The thing I like the most about it is its 60s sci-fi, the thing I hate the most is its 60s sci fi. By that I mean the 50s and 60s had some really cerebral sci fi writing, and some really shitty, cheesy ones too. Star Trek has both. Spcok is an awesome character, so is McCoy and Scotty, and the rest are pretty much meh. The Klingons are laughably bad and stupid looking for the most part, but the Romulans are pretty awesome even in this iteration. The Tholians are cool, and I even like the Gorn. I like the Andorians and Tellarites too. I even kind of like the intro/outro theme song.
Favorite Episodes are: City On The Edge Of Forever, Amok Time, Journey To Babel, Tholian Web, The Ultimate Computer, Balance of Terror, All Our Yesteryears, Errand of Mercy, Mirror Mirror, The Cage.
TNG
I don't think I need to go into why, but the show starts off pretty awful. For whatever reason the cheesy mid 80sness of the first two seasons is often even more cringey than TOS. There's only two, maybe three good episodes in its first two seasons. But that's not the part of TNG most people remember and go back to. By the first episode of the third season, the series got a massive increase in quality, both visually and in writing, and it became the giant cultural hit people still talk about. 90s TNG still largely stands the test of time. In many ways, it's my favorite Star Trek, in some ways not so much. When it comes to pure sci-fi storytelling, it's the best, when it comes to characterization and continuity, it falls behind DS9 by miles. Like with TOS, there's really only three main characters I really like: Picard, Data and Worf. I don't dislike the rest (well I hate Wesley, whos up there with Anakin Skywalker in infuriating characters), they're just not normally as interesting. A lot of the recurring themes and characters like Q, The Borg, holodecks, were all awesome, Overall, it's one of my favorite shows and it's excellent sci-fi, but I think it could have been better with more serialization and drama, but what little it had in those departments was normally good.
Favorite episodes: Hard to pick, since there's so many good episodes, but Q Who, Measure of a Man, The Defector, Yesterdays Enterprise, Best of Both Worlds, Family, Darmok, The Inner Light, Tapestry, Cause And Effect, Frame of Mind, I, Borg, Chain of Command, Drumhead, The Offspring, Parallels, Lower Decks, Pegasus, All Good Things. Probably a good deal I'm forgetting though.
DS9
The best of Trek IMO though when it first aired, I was a little kid bored with its dialogue and drama, and just wanted to see a spaceship meet aliens and travel the universe. As an adult, and rewatching this series, this one in some ways is leaps and miles ahead of even TNG. I love how the very first scenes of the show are the Battle of Wolf 359, I still rewatch that scene over and over again to this day. Its first two seasons are pretty boring, not first season TNG bad but not very engaging. By its third and fourth season everything starts getting really good with the reveal of the Dominion, manipulation of interstellar events starting coups and wars, and excellent character development all around. I don't think there's one major character of DS9 I dislike, I even like Quark and his family. The show wasn't afraid to step on sacred cows of Trek, and did it to advance storytelling possibilities rather than just to shit on the franchise. It used to be the blacksheep of the franchise but thankfully gets the praise it deserves nowadays.
Favorite episodes: Way of the Warrior, Duet, The Visitor, Trials and Tribble-ations, Paradise Lost/Homefront the six part beginning of season six, the whole nine part finale at the end, the three part introduction of the Dominion, For the Uniform, Chimera, really all the multi part arcs are good. The thing is DS9 is so serial its hard to just find individual episodes that are excellent on their own. In The Pale Moonlight is probably the best one.
Voyager
This is when things go downhill. Conceived as another new, dangerous take on Trek beginning in 1993, by the time it comes out in 1995, executives made sure it would just be a copy of TNG, in an effort to replicate the massive ratings and success TNG had. Its the only Trek series I watched from start to finish as a kid, and I loved it back then. Now, not so much. Of course it's a souless, decayed husk of TNG so that makes sense. Unlike TNG and DS9, it was a networked show, so that brought in all kinds of executive meddling, mostly for the worse. Add to the fact that Rick Berman and Brannon Braga were showrunners. Berman had helped clean up the mess of early TNG, but he was a rather conservative tv producer, and that's the last thing Voyager needed, someone who was already conservative who had his attitude reinforced by the success he had experienced. Braga was a good writer (for the most part) on TNG, but becoming showrunner clearly went to his head. Add to the fact that he became a pretty dry, conservative writer himself. He had cool ideas for Voyager that were often shot down by executives, but overall he clearly was getting rusty. The biggest sin is the show wastes its potential. Theyre all alone in a strange part of the galaxy, so make it seem like a pleasure cruise half the time! Theyre in this unexplored part of the galaxy, so make it full of aliens less creative than on previous Treks, and when that fails, just bring in species from previous shows! The Oompa Loopa Kazon are just lame rips of the Klingon, and the Hirogen are lame versions of the Predator, so eventually they just throw in the Borg.
The Borg are a major problem for many people, since they go through massive "villain decay" and were clearly just a ratings ploy and an attempt to make the show more like TNG. TNG treated them with great respect, not using them as a ratings ploy or making many episodes of them, even to a fault (the Borg were to appear in All Good Things in what sounds like a really cool appearence, but Piller shitcanned it). I, Borg is an excellent episode but it's not a proper follow-up to Best of Both Worlds, neither is Descent. We had to wait until one of the films to see them in their full fledeged glory again. What I'm saying is TNG understood the Borg and why fans like them. Voyager on the other hand just uses them like toilet paper because they couldn't think of a better idea half the time. But I think despite this, there's great Borg episodes and Seven of Nine is a good character, most ironically since shes just there for her tits. The Doctor is also awesome. But overall, while I don't hate it, it's not a good show.
Favorite episodes: Blink of an Eye, Tinker Tailor Doctor Spy, Year of Hell, Scorpion, Dark Frontier, Raven, Living Witness, Distant Origin, Unity. That's all I can think of right now, but still rewatching the series.
Enterprise
When things hit rock bottom, at least for most. The series that helped temporarily kill the franchise, but I don't hate it as much as many do upon rewatching it. It has a similar development history to Voyager. It was an interesting idea from Braga and Berman that was mangled by executives, and further mangled by Braga and Bermans conservative approach to writing and characters. What we ended up getting is a truly bizarre mess. Part of the show wants to be TNG (or really Voyager), part of it wants to be contemporary TV, part of it wants to be a throwback to TOS. Characters and even entire episodes are just carbon copied from Voyager, but it's hard to say which one I like less. Enterprise has the truy awful intro and terrible captain, but Voyager had a bad captain too, and the show was far more boring. I don't think the final season of Enterprise is the saving grace some hardcore fans make it out to be, but it is a major improvement from its first three seasons, and even then the third season is a major improvement over the first two. I feel the series was actually more the victim of bad timing and changing attitudes than just being a total pile of shit. I think if it reversed spots with Voyager, Voyager would have suffered the same fate honestly. I do actually enjoy Enterprise in the end, so to me this isn't Star Wars prequels level bad, but it's a low point for the franchise. Well, except for that laughably bad series finale. On a side note, the fourth season would fit well with today's love of continuity and obscure canon, so in that sense, Enterprise was ahead of its time.
Favorite episodes: Cogenitor, The Expanse, Twilight, The Forgotten, Zero Hour, Vulcan Three Parter, Romulan Three Parter, Terra Prime, The Augment Three Parter.
TL; DR: TOS is okay, TNG and DS9 are good, VOY and Enterprise are varying levels of bad. I hope Discovery is not another clunker.
