It's not often sequels surpass the first one but a few spring to mind.
- Superman II
- A Nightmare on Elm St III: Dream Warriors
- Jaws II -most people probably won't agree but I preferred it. It also had the best tag line ever.
- Rocky II
- The Empire Strikes Back
I'm not counting movies that were part of a triology/series(LoTR, Harry Potter).
Any others?
Really? Its a cool movie but better than the original? I always thought he best thing about part 3 was Dokken's theme song!
Wrong Turn 2 was better than the original.
