I think this is a new genre that they're all sort of working their way through it and haven't got all the kinks worked out yet but it's a genre that works for me.

Very very predictable, including the post credit scene !!!

It's funny, it's tense, it features two great performances from two actors and the director expertly creates a web of odd tension where you actually don't know what is happening for the majority of the run time.

The thing I enjoyed most about the film is the fact that it doesn't shy away from being a super-sized-cliche;
