Other crappy threequels:
- Superman III
- The Godfather: Part III
- Halloween III
- I'll Always Know What You Did Last Summer
Some decent three-quels (at least relative to the originals):
- Goldfinger
- Rocky III
- Mission: Impossible III
- X-Men: The Last Stand
- Lord of the Rings: Return of the King
Undecided:
- Rambo III (very violent btw)
- Star Trek III: The Search for Spock
It's interesting that the horror, action, sci-fi/fantasy, and superhero genres are the most likely to have a sequel. I know there are some good comedy sequels, but I couldn't think of any that went to III.
