Um... Iron Man had a midlife crisis, and while the movie wasn't specifically geared towards kids, c'mon. Are you seriously going to say a super hero movie doesn't have a bunch of kid fans idolizing this character?
Anyway, haven't seen the movie, not going to judge until I do (on DVD with my siblings, something I haven't payed for and can walk away from), but the series only dropped the ball for me with the third one, what with the new creative cast, so I'm going to be somewhat hopeful. With the ability to walk away.
