Scream

Scream is a Horror / Mystery movie where common sense exits early and everyone else is left to deal with the consequences. The rating says it has enough going for it to justify a look, provided the premise is your kind of trouble. Expect the obvious answer is, naturally, almost never the answer. It is not trying to solve cinema, cure society or earn a medal for restraint; it just needs the premise to work, the momentum to hold, and the audience to avoid checking the clock every six minutes.
