Star Trek III: The Search for Spock
I kind of feel that this gets a lot more hate than it deserves... because it follows Kahn and because it rewrites an emotional death. I know, I know, I love Spock too, but, really, should have left him dead. That was part of the emotional roller coaster of II. But, they didn't and that does sort of cheapen Kahn a bit. However, it's really not a bad entry on it's own. It's a solid film. It just followed the greatest of the bunch and pales in comparison.
