It's a mild crowd pleaser for people who are exhausted by blockbusters.

an ambitious but ultimately ineffective debut endeavor.

Go in cold, and you're likely to emerge with your blood boiling. This has to be seen to be believed.

Very good movie overall, highly recommended. Most of the negative reviews don't have any merit and are all pollitically based. Give this movie a chance at least, and it might give you a different perspective.
