I am glad I saw Hilary Swank's BOYS DON'T CRY back in 1999 but I would never see it again. It was an artful movie with good performances by Swank and Sevigny but seeing it again would put me over the edge. I could also never see PRIEST again for similar reasons. Torturing people for their color, sex, or sexual orientation is important to know about but seeing it on a big screen is another thing.
What would you never see again?
