My opinions on each of the series:
TOS: Really good and obviously is the most Star-Trekky, but it's often let down by the fact that they didn't have a sense of continuity yet. Like in many episodes they claim different substances are the strongest known to man. Then in another episode they have a truth serum that is never mentioned ever again. I love the formula it used though; Enterprise encounters something strange, they investigate, can't save the day, Scotty pushes it, they save the day. It would have gotten stale eventually so I'm glad it finished when it did.
And while episodes such as the Nazi Planet or Yankies/Commies Planet episodes seemed cheesy, can sometimes be quite good, so long as you look past a lot of the really dumb stuff that's in there.
TAS: Only ever seen two episodes of this so I can't really have an opinion on it. From the episodes I've seen it wasn't vary good. I think they got kidnapped by some McDonalds fries or something.
TNG: My favourite series. I know a lot of people say it would have been better if it didn't portray humanity (and often the rest of the Federation) as already having achieved the perfect society, but it didn't really show Earth all that much at all. On the flagship of the Federation they're going to only have the best, I'm sure not everyone is as mature as Picard. What I really love about the series though is how it manages to be exciting without having all that much action in it. The Enterprise rarely ever got into a massive battle, even in "Yesterday's Enterprise" when the timeline is changed and they've been at war with the Klingons for years, there isn't that much of a big battle even though it's a warship.
In addition to all this I generally like the layout of the Enterprise. It's nice and bright on most decks, lots of room on the bridge and engineering. I had a better sense of where things were than in the original series too. Was the red trapezium thing in TOS the warp core? I dunno.
DS9: I barely ever have a chance to watch this as it's either never on, or it's on when I'm at school. I generally don't like darker shows (darker in the lighting sense), and since DS9 is pretty brown and beige everywhere I was put off for quite a while. When I did get around to watching some of it I really liked it though. It was good to see them stray from the "planet of the week" thing that the past series had been doing.
VOY: I do quite like Voyager too but I don't like it as much as TNG or TOS. One big reason for this is because it went from "We've got to get home!" to "The Doctor, Captain Janeway and Seven of Nine Show". It barely had any character development for anyone else. Not many of the other characters were very good anyway. Chakotay is pretty boring, when he's on an away mission but isn't the main character of the episode, I generally can't stand to watch it. Then there's Harry Kim. I quite like him but he never does anything interesting and the crew care so little about him that when he dies in one episode they act as if everything's normal since they have a parallel universe version of him.
Don't even get me started on the Borg. In TNG they were the biggest threat ever; one cube could destroy all of Starfleet. In Voyager, one Intrepid class ship could destroy the entire collective. I'm not saying they shouldn't have included the Borg, but they shouldn't have made them into the race of bees that don't consider you a threat despite the fact you've beaten them hundreds of times already.
ENT: I can understand why a lot of people hate it. There are quite a few good episodes but there are far more bad ones than the other series. It might have to do with the fact that you know they're going to win since the rest of Star Trek happens in the future. My favourite episodes that can stand by themselves and don't rely on any other episodes (in fact this applies to each of the series and most of the movies as well). My favourite one would be "In a Mirror, Darkly" since it doesn't rely on any other episode except for maybe "The Tholian Web", but that isn't necessary. I really disliked the whole Xindi arc though, since it just felt like it was dragged out and the fact that Earth isn't destroyed in the future takes a lot away.
cuz the 2009 movie has some other thread or somethin, idk.
that being said the 2009 movie was probably the best star trek movie ever made. also it was on a different timeline
Nah, I wouldn't say it's the best movie. It's definitely good, but it doesn't beat II, IV or VI in my opinion.
Something that I want answered about the 2009 movie is this: the stardate system is changed so that it corresponds to the Gregorian year. However, when Spock asks the Jellyfish Ship for its stardate of manufacture, it replies with the year as in the new format, but since it was built in the original Trek timeline, it should have responded in the old format.
I can't believe how old TNG really is, it doesn't even seem like that old of a show, but here's a somewhat recent picture of some of the cast.
dunno who the fatso in the middle is.
Who's the guy in the back? Also wtf is up with her nose?
