Less is more
I think this is a rare film, in that it delivers a strong message -- mainly that a person's wealth, position or status in society has little to do with that person's pureness of heart/willingness to commit evil -- without using preachy or heavy-handed melodrama to get that message across. In other words, less is more.
I don't understand why...with both Sean Penn and De Niro cast as the main characters...this film didn't get more attention.
