10. Star Trek V: The Final Frontier (1989)
It's a widely known fact that science fiction and religion don't go too well together in movies. Odds are you'll offend half the audience and alienate the other half. Few films have ever been able to successfully blend those two elements. This movie comes close. It follows a Vulcan named Sybok who is convinced he can find God in the center of the galaxy, so in order to go there he needs to steal a starship. Specifically, the Enterprise-A. The story was written by William Shatner (who also directed) and it was
so close to being a good movie. Unfortunately, the budget was slashed repeatedly until finally the visual effects were a joke. Similarly, before the story was adapted into a screenplay there was a writer's strike, so eventually the job of writing the screenplay fell to a man who had only one credit to his name.
The Good: A unique story with touchy subject matter that was handled surprisingly well, and William Shatner actually seems to be a pretty good director.
The Bad: Rushed production led to a very inferior final product, and a few wholly unnecessary scenes.
The Ugly: The aforementioned visual effects.
