F.3.A.R would have to be my disappointment, i loved the first 2, especially fear 2 since it had a decent back story and the game-play and jump scares were great, but i couldn't get into fear 3 no matter how hard i tried, Also just to add a movie sequel that i was disappointed for was aliens vs predator - requiem, it was supposed to bring back the franchise, the first movie with a Predalien and you could hardly see it through most of the movie.
