Query: Disappointing!

The great press touting "Blood Diamond" led me to expect a film with the depth of insight into the politics and social consequences of the diamond trade that I found when watching "Hotel Rwanda." The latter was chilling in its realism of the international politics connected with this genocide and excellent in portrayal of its characters.Not so with "Blood Diamond." For me, nothing in "Blood Diamond" redeems the film's failure to depthfully unmask the price paid by everyday African workers for a commodity that we so often use to symbolize the "good life".It is a film heavy on bloodshed, threats to survival and brutality. Characterizations are lightweight. The African father, in particular, should have been portrayed with a great deal more depth. His character was so obscure and marginalized that there was no preparation for his actions at the film's end.In short, on all counts -- I was deeply disappointed. The best I can say of it is that there is plenty of action.
