It is a performances centric movie

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

I really wanted to like this movie. I feel terribly cynical trashing it, and that's why I'm giving it a middling 5. Actually, I'm giving it a 5 because there were some superb performances.

The film never slows down or bores, plunging from one harrowing sequence to the next.
