7.5 stars!

While I can't say I've seen everything he's done, this certainly stands out to me as the best acting I've seen Charlie Sheen do. I can't help but be curious how accurate the portrayal of the character and story is (it's based on a true story), but given the nature of it, I don't see why they'd have to exaggerate or take license with anything.

It may seem to start slightly expeditious, but it doesn't feel rushed once it gets going and, again, it's a true story and screen time is limited, so it really does a great job of setting everything up and getting the viewer into the bulk to the happenings and through them.

Great atmosphere, well-paced. Raw and engaging. A good script and the directing is more than solid in every aspect (he gets TOPS out of all of the actors, the use of music and sound is outstanding, non-intrusive yet evocative camera work, etc.) It's somewhat minimalistic which allows the great acting backed by all of it to shine through. It almost feels like a play in the desert.

If you've thought to yourself "eh, Charlie Sheen in some crime movie? looks like B-cheese I'll pass" or similar, you should re-consider. It's not easily-digestible crime-actionflick fare either.

This movie is serious, dark, and kind of like a surprise hit in the gut if you aren't ready for it.
