Have to disagree with you there, I liked the premise that Michael Myers was gone after 2 and the studio would produce a new story every Halloween. Shame people had such a hard-on for him and brought him back to star in sequel after crappy sequel, the film was pretty cheesy and has a crazy plot from Scooby Doo but some scenes were amazing! What other film has had a scene as terrifying as the one where a young kiRAB head melts into a pile of bugs, spiders and a rattlesnake (which then goes and bites/kills the parents)?
Some of the sequels mentioned so far make me realise how privileged some people's movie-watching has been. I mean THE DARK KNIGHT? GHOSTBUSTERS 2? COME ON!! Ever seen Blues Brothers 2000, Jaws 3D, The Exorcist II: The Heretic, Ringu 0, Alien Resurrection, Cube 2: Hypercube, X-Men 3: The Last Stand or The Lost Boys 2: The Lost Tribe? All the original films were great and the sequels screwed it up BAD.
