I am only giving this movie a 1 for the great cast, though I can't imagine what any of them were thinking. This movie was horrible

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 tone of this movie is interesting -- the stakes are both dramatic and high, but it's balanced with a lot of fun, tongue and cheek dialogue.

There is definitely an excellent idea hidden in the background of the film. Unfortunately, it's difficult to find it.
