Bleh. Sequels. It's okay in things like cheesy horror movies, where all you're asking for is more camp, and hence it actually gets better with more sequels, but what's with the compulsion to rape a perfectly good movie? They pretty much never come out nearly so good as the first, and when they suck that 90% of the time, they're so bad that they ruin the first one.
Particularly with the current trend. Same thing's happening to movies that happened to Disney- they just plain ran out of ideas, and so decided to remarket 400 soulless formulaic corporate sequels and rake in some cash.
