Turning the other cheek is soooo 6 months ago. Looks like Mel Gibson is back on more familiar ground. His new production, "Paparazzi," would seem to be the good old vengeance-enabling tale of a man so wronged by evil-doers that he's free to inflict as much harm as he wants in response. There's only one good reason that allows us to kick so much ass with impunity: because the other guy deserves it. Sure, that means we depend on the existence of evil-doers to fuel our catharsis and give us a reason for living, but it's good entertainment right?
