Self-important, over-dramatic, uninspired.

I have absolutely never seen anything like this movie before. You have to see this movie.

Unshakable, witty and deeply felt, the film will be paying emotional dividends for a long, long time.

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.
