1. Star Trek 09-Credit due for a new producer who made ST feel like well...ST again. Adventure, scale, cache', all missing from previous Trek movies. If all that's not enough, it's writing brought some small development to characters that basically didn't change much in the original series, executed well enough to be nominated for a Hugo, Nebula, Writers Guild Award, a trifecta not accomplished by any other Trek movie.
2. Wrath of Khan- Previously the best ST movie. Good characterization, and a movie that makes up for an underwritten bad guy role with terrific performances by everybody! Still contains the best space battle ever.
3. First Contact-Admittedly, not a perfect film, and not the best Borg story by a long shot but it also offered a multi-leveled formula for success: history, time-travel, almost elemental enemies, and something rarely seen..a personal vendetta for Picard.
4. Voyage Home-Not completely coherent but a fun movie with no significant strikes against it. Did I mention fun?
5. Nemesis-Again, not a perfect movie, that I'd have re-written myself somewhat, but it's a major improvement in scale and pace over the previous STNG movie as well as the recent TOS ones.
6. STMMP-DE- Ok here is where I change my mind occasionally..sometimes STIII feels more statisfying as a movie, but the new DE is an improvement over the original...its a tighter movie. Hard to beat for FX and music (both nominated for Oscars)the story feels slim, but the philosophy behind it wins the day.
7. STIII- So STTMP improves upon TOS with a story that takes AI seriously, and tried to include Spock in that as a personal link...STIII again uses Spock but in a story whose philosophy is bizarre and very un-Treklike...postulating souls that come back to life...must have had theists as well as non-theists perplexed in it's day (I was 14 and just knew I liked Spock being alive). There are good moments and ILM does a great job on a small budget (one that used fewer FX than many made-for-tv movies, as well as STNG 3 yrs later). Ultimately it can't compete with some ofthe better Trek movies.
8. Undiscovered Country-Marginally better than #9 on my list. Not a movie that withstands the test of time well.
9. Insurrection- Underrated, certainly not a terrible movie. Lacks scale and a sense of urgency.Gains points for a plot that's still debated amongst fans today.
10. Generations- A complete mess of a script. The most inconsistent of all stories. It's few pluses can't make up for a scattershot mis-fire of a movie.
11. Final frontier- The movie that shall not be named!

Though I am naming it bad. Problems begin at the start of a poor concept, terrible dialogue, dumb humor, horrible FX, old actors looking tired. This is what happens when the studio doesn't throw out a clearly horrific script...possibly because of the success of STIV and STNG.
