Strong:
-Use of camera: Man the shots are so deliberate in terms of framing you have no idea. I could swear that at one point when there was a fireball on screen, I felt the heat. I know it's impossible but I swear it.
-Acting and casting: Yeah, it's not Iron Man, but it fits perfectly.
-Action: It's the HULK! Big green monster with gamma infused cells. Banner=Acting and trying to find a cure while dodging bullets.
Hulk=Smash! Smash! Smash!...trust me, you'll find yourself cheering for the green guy during the final fight.
-Balanced
-Falcon Kick: There's two of them!

Weak:
-Beauty and the Beast moments are corny as all get out, but they're not overplayed.
-Pacing: Just because it's balanced, doesn't mean it's paced well. Some things make you go 'huh?' and then quickly dismiss it as the action picks up.
Different from Iron Man:
-Humor: Not as much, but still quality. Different type of humor too.
-Stark:

-End Credits: Nothing, don't waste your time, there's nothing at the end.
So yeah, there really isn't much to criticize with this one. It's a lot of fun, and if you look deeply into it, you're looking too deep into it, and if you're just looking at it for the action, you're not looking at it at all. Like I said, it's balanced, it's fun, it's good. Go see it. Zanzibar!
[Also I finally saw Speed Racer, but my comments on that to come in the Speed Racer forum.]
