I'm curious. Do you guys root for the gang members in Assault on Precinct 13, or the vampires in From Dusk Till Dawn? Both of those are examples of the "heroes" in the movie being essentially bad guys. Attack the Block was going for the same feel. Start out with some villains, then show some REAL villains, and have the protagonists (the cop in Assault, Harvey Keitel's family in From Dusk, and the woman in Attack the Block) have to team up with some despicable characters for survival. It's a moral dilemma.
