Violence at the Movies

There's a film that is in limited release called "Chaos." By all accounts, it borrows heavily from "Last House on the Left." Roger Ebert savaged the film for what he called its "heartless cruelty." The film's director and producer responded to Ebert's criticism, and he in turn elaborated on what he thought was wrong with the film and why.
I'm not taking sides on this. Indeed, it's my nature to run right out and watch (or read or listen to) whatever it is someone says I should avoid. However, I thought this was a fascinating discussion, and I thought I'd share it.
