First off would be Halloween, easily. Mainly because Halloween (1978) is probably one of the top 3 best, and scariest horror movies ever made and most of the sequels have been at least better films than any other horror franchise sequel. Aside from 8, 6, and 5 (which i still found to be at least quite entertaining, even though it's obviously a bad film) all of the sequels and even the two remakes have slayed me. Secondly would have to be Scream. Not a single bad film out of the 4. Every sequel was at least as good as the last.
