A lot more amusing than I thought it would be.

The performances transcend the film's tropes, grounding it in characters that feel more complete than this subgenre often produces.

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.

A great movie, one of the best of this year. There was a bit of confusion at one point in the plot, but nothing serious.
