I'll never understand how the same people who love ST IV hate ST V. "Voyage Home is funny, but Final Frontier sucks." They're both goofy as hell, and how is going back in time to the 1980s any less stupid than searching for God?
My list (Based simply on which movie I'd rather watch, not which is better):
1. ST II: Wrath Of Khan (natch)
2. ST VI: Undiscovered Country
3. ST IV: Voyage Home
4. ST V: Final Frontier (At least before RiffTrax. I'm pretty burned out on STV now.)
5. ST: The Motion Picture
6: ST III: Search For Spock (Just never liked it.)
And if you want to include Next Gen movies, stick First Contact at #3 and pretty much burn the rest. Now give me a DS9 movie! Yeah, right. That'll happen.
I never said I didn't like Star Trek V. I like it quite a lot, actually. It's just that it's not as good as III or VI. But it's definitely better than, say Nemesis, and slightly better than Insurrection. Though it's probably on fairly equal footing with Generations, and it's not as good as First Contact. And let's face it, the worst Star Trek movie is still billions of times better than the best Rob Schneider movie. (Not that I'm saying there's such a thing as a GOOD Rob Schneider movie, but chances are that at least ONE of them is slightly less horrible than the rest of them.) And Star Trek V has some of the best character moments in all of the movies. Say what you want about Shatner, but in his Star Trek movie, he let all of the supporting cast get their chance to shine. And it has one of Spock's best moments in the series -- the part when the Klingon General is reluctant to help Kirk, saying he's just a foolish old man, and Spock says "Damn you, sir. You will try." Or the part with McCoy's flashback to his father's death. I tell you, DeForest Kelly was the unsung hero of that cast.
