What are some sequels and prequels you feel are underrated and either get an undeserved negative reception or not enough recognition or credit? They don't have to be as good or better than the originals, just films you feel deserve a better reputation than what others typically make it out to be.
Some I find are underrated and solid films:
Ghostbusters II
Indiana Jones And The Temple Of Doom
Predator 2
Iron Man 2
RoboCop 2
Die Hard 2
Jaws 2
