As long as the sequels were done right with a good cast and good story to continue.
Lost Boys 2 the original sequel aka Lost Girls - I would watch it as long as it had a good decent female cast as the vampires and return of Corey Haim when he was in better shape. This true sequel was in talks for like what? 15 years?
The Stuff 2 - yeah it would never ever happen but I still love The Stuff
Nightbreed 2 - tone it down with the gore then I would see it.
Big Trouble in Little Tokyo - sequel to Little China. This time the sequel involves Tokyo town in New York or wherever that involves ancient Japanese supernatural stuff
Maniac 2 a true sequel that takes place after the original Maniac. Kinda like what went on with the first two Psycho movies.
Fright Night 3 - imagine Peter Vincent and whatshisname taking on vampires all over again with a few twists. They have to deal witih other things besides vampires.
Witchcraft sequel - how many has it been now for those Witchcraft movies?
