If you looking for roughly sketched characters then this is your film. Like the film itself the central protagonists survive only on pace and violence. Unexpectedly unbloody, City of God's main saviour is its reliance on flashback and quirky narrative that owes much more to early Hollywood gangster flicks of the Bogart era than the Scorsese style many critics enthuse about. Worth a look - you'll certainly be kept on your toes.
