The Best:
1. Star Trek II: The Wrath of Khan--This movie has rich themes and speaks to the human condition while mirroring the advancement of technology and the improved warfare of history. It talks of sacrifice and friendship in a very logical manner.
2. Star Trek: The Motion Picture--An inventive idea having a machine of our creation that wants to make the next leap into consciousness. In a million years I couldn't come up with this storyline.
The Good:
3. Star Trek (2009)--A fun version of Trek where we get to see Kirk, Spock, and McCoy immature and very gifted. There is no seasoning in these characters. There are plot holes. I wish I could take out all of Nero's dialogue and learn what's happening from Prime Spock. The wormhole is there for 20 years, but does it expand? Does more red matter mean a stronger magnetic field? I have questions, but it was the most fun I have had in a movie theatre at Star Trek (17 years) in a long time.
4. Star Trek III: The Search for Spock--Good picture in its execution, even though I don't like how it affected the rest of the Original Series movies. The stakes are high, it says something about friendship and putting Kirk in the position Spock was in in II. It's interesting to compare the two characters' reactions.
5. Star Trek VI: The Undiscovered Country--While it is a flawed movie and the prison planet scenes are all but unwatchable, it is well-written and the acting is good.
6. Star Trek: Insurrection--It actually does some exploring, has an interesting moral dilemna. A very underrated version of Trek.
The Bad:
7. Star Trek: Generations--Some very bad acting in some parts of this. For instance, Troi and Picard talking about Rene. Hokey pull-at-your-heart-strings nonsense like a little girl losing her stuffed toy. This movie seems geared towards 1994's 10-year-old audience.
8.Star Trek IV: The Voyage Home--Fun, yes. Ruined the movie franchise as far as I am concerned. Some punishment for Kirk.
The Un-Trek:
9. Star Trek: Nemesis--Overtly dark, disgusting, and a supervillian adds to the descending night of the 24th century. Bad movie.
10. Star Trek: First Contact--Space monsters, a zombie queen seducing Data, and a psycho Starfleet Captain who suddenly puts down the crazy after one conversation. Oh, and they tell Zephram Cochrane how great he will be. Horrible.
11. Star Trek V: The Final Frontier--Campy humor, a bad script, and worse acting (especially by Sybok). A deeply flawed movie that seems to re-tread on the Motion Picture.
