I saw the Lost preview. Though I don't remember much about Iron Man other than what he looks like, the effects look good, Robert Downey Jr. is in it, and they played the Black Sabbath song, which made me chuckle. I'll probably see it, but not right when it comes out. That way I can spare myself if it bombs like other comic movies... (I'd just wait to see it on video to save money if this were case.)
