Blood Diamond - true story or Hollywood exaggeration?

This film is brilliant. I had no idea what to expect, apart form a diamond thriller across Africa, and what I got was a conspiracy/civil-war/family/love extraodinaire of the quality of The Constant Gardener or Hotel Rwanda. Leo is fab as an ex army diamond smuggler with a heart, and there is some nice work from David Harewood as the evil one-eyed leader of the rebel force, but the real performance comes from Djimon Hounsou as Solomon Vandy. Being ripped away from his family to work the diamond mines of Sierra Leona, his story to find the enormous pink diamond he buried and re-unite with his family is heartbreakingly sad and exquisitely told. And it makes you want to do something to help, which is always the mark of a good movie. It changes you, and so it should.
