Veering off-topic for a moment...
I think its funny you guys are comparing "The Incredibles" to other Superhero movies. The Incredibles was a cartoon meant to be funny, the movies you are comparing them too were meant to be dramatic. Apples and Oranges people.
I would actually argue otherwise. Yes, it was made by Pixar, who historically has done cartoon-oriented CGI flicks, but the Incredibles was different, IMHO. They brought Brad Bird on to direct for one, and frankly I don't know if it was that or other coincidental factors, but for me the movie rose above the standard (if still excellent) Pixar cartoon-like affair into a dramatic movie of its own right.
A warm-hearted movie, definitely with plenty of humorous moments (it *was* spoofing pretty much any superhero movie, comic and cartoon, after all), but still a dramatic movie nonetheless.
But then, maybe I just got lured into it, dunno.
Personally, my favorite moment was the whole launching the missiles at the plane deal. Between music, direction, writing and excellent rendering, I really did forget I was watching a CGI flick for a while.
(and to veer even farther off topic) I actually had a discussion with my brother about the Incredibles just the other day (he's teaching an animation course at a university). My argument was that animation was just another medium, and just like any other medium it can be used to tell whatever story you wish--comedy, drama, family, whathaveyou. Simply because animation has historically been used for family comedy/kid movies doesn't mean it can't be used for other stories as well (a concept that sci-fi fans should be quite familiar with, esp. B5 or Firefly fans...see? I brought it back on-topic!!)
OK, that's enough for now...
