I agree that Al Pacino was a terrible ham in "Scent of a Woman." (And I love Al Pacino. "Dog Day Afternoon" Al Pacino.) Was Dustin Hoffman really terrible in "Rain Man"? He was certainly annoying, but wasn't that the point? You know who was even more annoying in "Rain Man" than Dustin Hoffman? (I ran across it on TV the other day, so this is fresh in my mind.) Valeria Golino. I was going to watch that movie again, but she drove me up the wall. Sorry, that's off the topic of actors, but I just wanted to nail down that one little point of personal opinion, and I get to do things like that because I'm blllllogggggggingggg.
