This Matt Damon-Jimmy Kimmel confrontation happened a week or so ago. What’s wrong with it, of course, is that it’s an act. It would have been brilliant — historic — if Damon had really gotten angry and stormed off. It would have been something real and rude instead of another damn mock- ironic put-on. Everything is on this level these days — on talk shows, SNL, sitcoms. Nothing laid on the line, every statement in “quotes.”
