I know i'm in the minority on this, but my favorite trek movie to this day is still Star Trek V The Final Frontier. To me, it is the most like an original series tv episode. Where the crew go out to explore. Sure, the budget and the effects were terrible for a big budget movie, but i never let special effects get in the way of my enjoyment of trek. Otherwise, i wouldn't be able to get past watching the old TOS, which had just as bad effects. My favorite scene of all the TOS movies is the Sybok/Kirk/Spock/McCoy observation lounge scene. That got to the heart of so many things that trek is about. I love Kirk's speech to Sybok in that. I probably re-watch this movie more than any of the other trek movies.
