i know i wasted 90 mins of my life.

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.

There's a more than satisfactory amount of boom-boom in the movie's trim running time.
