17. STAR TREK V: THE FINAL FRONTIER (1989)
My favorite Trek joke goes ''What do they call Star Trek in Japan?'' Answer: Sulu, Master Navigator. My least favorite? The Final Frontier. Who else but William Shatner would show, in a film he's directing, a scene of himself manfully climbing Yosemite's El Capitan? Trek V is an oil slick of spiritual hooey in which Kirk meets God face-to-face, then sasses and back-talks him. In an irony probably lost on the hubristic, hairpieced auteur, God looks like atheist Karl Marx.
