...but honestly, not because of the action. Don't get me wrong, the action was great. The CGI didn't get in the way. The booms were gorgeous war pron. But the acting, the dialog, the whole script was fantastic. Who would have thought that a scene with Tony Stark and his robots would steal the movie! Oh, and a note for fans: there's a Ferris ending. SIT THROUGH THE CREDITS! Even if your bladder is about to go 'splody!
