15. Babe: Pig in the City (1998)
A cute, if surreal, concept is taken too far in this ridiculous sequel.
14. Grease 2 (1982)
No Sandy, no Danny Zucco, but some sub-standard songs and teen-movie mugging that shows Michelle Pfeiffer's humble beginnings.
13. Rocky V (1990)
Arguably, 2006's Rocky Balboa was a relatively decent movie. So we'll stick to number five in the franchise, where Rocky is past his prime but must return to the ring because he's lost all his money. A hero grows old and slightly pathetic.
12. Jaws 3-D (1983) and Jaws: The Revenge (1987)
Jaws made beach vacationers in the '70s genuinely afraid of the ocean. It was campy, but also effectively scary. Jaws 3 & 4 were just campy, and not in a good way.
11. Ocean's Twelve (2004) and Thirteen (2007)
Steven Soderbergh's 2001 remake of essential Rat Pack movie, Ocean's Eleven, may not have been brilliant cinema, but it was entertaining. Its cash-cow successors, however, were not.
