I became disenchanted with Mel Gibson when all his weird X-treme Catholicism beliefs came out around the time of The Passion. And when he was arrested and spouted his anti-Semitic and sexist remarks, I was Out. And now that we've heard more evidence of his ugly personality... bleh. Bird on a Wire is on TV and... bleh.
I apply a certain amount of disassociation between an artist and their work, but there gets to a point where the artist's life becomes Unignorable. Mel! You're just GROSS!!!
