Hulk is going to be completely redone, nothing like the trash from the first one.
Darknight looks great.
I'm not a huge Iron Man fan, but I saw a preview when I rented Beowolf... it looked really good. It's one of those "beginnings" movies (which tend to be the best). Downey actually was a perfectly cocky Tony Stark. He builds the first generation suit to escape some terrorists (who kidnap'd him)... the suit is very raw and brutal. Then he builds the elaborate one.
Until I saw the preview, I wouldn't have been all too interested... but that was one great preview
XMen: Wolverine... "Xmen" in title only, this is all about wolverine.
