There are 3 previous installments of this franchise, and this is more of the same. This movie has one and only object, to tense you up and the scare you and it delivers it. I have to say, I've never seen a whole theater scream and jump like I did last night on the final sequence of the movie. It is dumb to judge all movies by the same standards. If you want a good history and flawless direction go see Argo... If you want to scream watch this one.
