TOS was before my time. I've seen a few episodes, but it's not anything I crave re-watching. Star Trek: The Motion Picture was ludicrous and horribly boring. The Wrath of Khan is a classic, of course. There's not much memorable from ST3 aside from Lazarus Spock, bad weather, and Kirk's demotion. ST4 made me want to cut myself, harpoon a whale, and litter. ST5: The Final Frontier was, well, a bearded man leading a cult in a fabulous dress -- not my thing, really. The Undiscovered Country was my favorite movie based on the original series by far. I really liked that every villain believed he was acting for the greater good, and none were insane or evil for evil's sake. That's the best kind of story I think, when one can understand what drives the bad guy.
TNG was my time. Although I tend to skip every episode involving Alexander Rozhenko or Lwaxana Troi, I'm always most interested in the episodes involving Worf's development -- his internal conflict between duty and heritage, his fall from grace, and his unshakeable honor. I agree with Gene about the impossible odds presented by the Borg conflicts, and I always enjoyed the episodes with Q. Like Cos, I even got into Wesley Crusher's progression from annoying distraction to respected bridge crewman, and his eventual apotheosis. By the end, I was disappointed not to learn how much further Wesley would progress. Favorite Next Generation movie was Nemesis I think, although Data's doom felt like little more than a contrived excuse for Brent Spiner not to have to wear gold makeup any more. Still, Patrick Stewart's performance on the subsequent bridge scene draws a tear every time I watch it. First Contact comes a close second, but loses due to Zefram Cochran's douche baggery and the Enterprise crew's implausible naivety regarding it.
DS9 was an excellent series, worthy of binge watching. The many conflicts were cleverly developed and well executed. I could do without the Grand Nagus episodes, though -- inconceivable as that may be. (See what I did there?).
I never got into Voyager. Neelix made me want to set fire to my eyes. Whatever did that pretty little blonde boy see in him, anyway? I've never seen an episode of Enterprise. It just doesn't feel right to see Scott Bakula without Dean Stockwell at his side performing percussive maintenance on a misbehaving Game Boy.
Anyway, the new Star Trek cinema reboots have shown promise. The first one seemed clever, showing the crew taking completely different paths to arrive at the same destination as the original series (albeit minus a rather important planet). It also felt like cheating at the same time, though. Really? Hollywood is just going to do the whole series over, justifying it with a wave of the hand and time travel gone awry? The second was a nod to the classic Khan, but this time with a better demonstration of Khan's canonical enhanced abilities and intellect. Also, Bumbersnatch Crumpleplink can do no wrong, so cheers for the casting there.
So far, I'm digging the reboot movies. They've got a higher batting average than the original series movies. I hope the third doesn't screw up the streak.
I'm getting bored with Star Fleet Headquarters being attacked in every movie, though -- and it's going to happen again in the third one, if I'm inspecting the trailer accurately. You really don't have to keep doing that, J.J. But thanks at least for not hugging any trees or saving any whales.
