Although it has its amusing moments, in eneral the plot does not convince.

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.

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.

There are moments in this movie where the great movie it could've been peek out... They're fleeting, here, but they're worth savoring, and they happen often enough to make it worth your while.
