Okay.. I saw it yesterday, and must say that I had a good time. But the movie had so many weaknesses that I felt a bit let down after all the hype this movie has generated. The pacing was weak at points, the villains were weak, the opposing forces were not derivative and not menacing enough.

Warning: Spoiler! (Click to show)For an extraterrestrial, other-worldly invading force, the aliens were just dumb cannon fodder, and the chinese-lion-dance-costume-esque transport ships were cheesy and too much reminiscent of SFX stinkers like Skyline, and Transformers 2 & 3.
The interactions between Thor and Loki were melodramatic, and at times Loki appears to be an extremely powerful demigod, and at others, a whiny, emo punk with brother and daddy issues.
On the other hand, I absolutely loved how all the superheros got equal footing, and the banter between them was fun.
Seeing the stupendous box-office success of this movie, I am a little sobered to see The Dark Knight overtaken by this, and saddened by some other undeserving stinkers (Alice, Transformers: DoTM (puke!), the Pirates dreck, etc.)
I hope the sequel does better at the story front. I personally would put the first IronMan movie as the best of the Marvel superhero flicks so far, closely followed by this one.
