I have to lean more on the side of VINH on this one. Obviously he was extremely offended by the things Mel Gibson said, and you have to admit, they were some pretty awful things; so when he see Mel Gibson, he thinks of the things he has said. So why would he want to watch a movie where he is going to stare at Mel Gibson for two hours, even if the movie is one of the best movies ever made (a distinction that doesn't really fit any film Gibson has ever been in or directed), negative feelings toward the actor would ruin the whole thing?

Personally, I feel the same way about some actors, fortunately, they are the types of actors who only play in overly popular Hollywood daily shit quality films, none of which I have ever been the slightest bit interested in seeing, and therefore never had to worry about their faces ruining an otherwise worthwhile film for me.
