Time Out says
‘Blood Diamond’ inspires more than a few back-handed compliments. It doesn’t entirely evade the issue at its core – conflict diamonds – in favour of pure action by way of guns and planes, thrills and spills; but it hardly embraces the subject fully either. Similarly, it doesn’t entirely shy away from showing the brutality of conflict in Sierra Leone – there are terrifying depictions of child-soldiers in battle and of limb amputations – but neither is it daring enough to present Archer solely as a villain. By the final reel, we’re expected to detect a heavy dose of redemption and regret in Archer that’s about as plausible as baby-faced DiCaprio playing a tough mercenary of many years service. Final scenes in London in which diamond-dealing head-honcho Michael Sheen glides through London in a limo like a Bond villain are risible. Expect very little in the way of ideas and debate, and a lot in the way of action set-pieces, and as a lesson in distant suffering for kids or the unenlightened, it’s not so bad.
