1. Wrath of Khan-One of my favorite movies of all time. Very little action, but still moves at a fast pace with great performances and thematic weight. Also has my favorite Star Trek theme
2. The Undiscovered Country-A great and fitting end. Agree that it should have been Savik, but the writing was otherwise sharp and the film felt important.
3. First Contact-The only good TNG movie, but still very good. Good action, good to see the Borg again, and the context of the first warp flight just worked.
4. The Voyage Home-Stupid plot, but so much fun
5. Star Trek 2009-See above
6. Into Darkness-Also see above
7. Search for Spock-A number of good elements (Christopher Lloyd as a Klingon, the stealing of the Enterprise, ect.) that don't jell together because the movie is so focused on undoing Wrath of Khan.
8. Nemesis-A few great moments, but otherwise forgettable.
9.Insurrection-Completely forgettable and bogus morals.
10. TMP-Love the initial shot of the Enterprise. Bored to tears by the rest. Stilted writing for what could have been a decent plot.
11. Final Frontier-2-3 good moments, but otherwise horrible.
12. Generations-It's like they were trying to say 'f-u' to all their fans. Makes Final Frontier look well thought out. Kirk and Picard team up to beat up an old guy. The Enterprise D destroyed by an out of date Bird of Prey. Reusing footage from other movies. The stakes being a primitive world we don't even see. And the whole plot is because the villain is too stupid to realize he could just launch himself in a space suit instead of blowing up stars. The Phantom Menace is Citizen Cane compared to this steaming pile of crap. Not only the worst Star Trek movie by a wide margin, but one of the worst big budget movies of all time.
