Simple and well acted, it has tension enough to knot the stomach.

A lot of perfectly good film show their cards early, establish a unique premise and let the audience explore a topic at a leisurely pace, without much in terms of surprise. this film is not one of those films.

It is encouraging that the film ends so strongly.Otherwise, it wouldn't have been a particularly memorable film

If you like to be scared, if you like to laugh, and if you like to learn a thing or two at the movies, this absolutely cannot be missed.
