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

a film so unique, intoxicating and bizarre that it not only demands another viewing, but is also forgivable as a satirical comedy where the jokes eventually take the back seat.

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.
