100 plus better than a recent caper-like movie I've seen (Duplicity-yugh) but it did have some semi-graphc violence, like when a character is shot in the head, but it's brief. The language in today's terms would definitely earn a PG-13, but that didn't bother me any. I haven't seen any other movies from 1973, but this one probably deserved the Best Pic win.
The Sting is actually a good movie, good for kids who don't have a problem with swearing. It is an interesting movie because the main character is actually not a very good role model, I liked it though.
