I absolutely adored the film. I think the only two things I disliked were Mark Ruffalo's acting when he wasn't green, and the way Black Widow was handled. Way too much focus on her body, not enough on her character and personality. A shame, really, because those have great potential.
Other than that, it may well be the best film I've ever seen.
I'm way late on the response here, but I LOVED it. I saw it three times, and wish I could have afforded to see it some more. I usually really dislike the Hulk and find him annoying, mindless, and destructive, but they just made him so damn likeable! I, unlike Stephan, really loved Mark Ruffalo. He was probably my favorite one, honestly.
Agreed, though, on the Black Widow thing. When she was interrogating Loki all I could think was, "DAMN, DAT ASS."
I'm going to be shunned for this, but I saw Avengers once and, quite frankly, that was enough. It was a good film, and maybe I just don't get it because I lack knowledge of comics and didn't even see any of the previous ones except for Iron Man. Oh, and I know precious little about Joss Whedon. But yes, I enjoyed it. I laughed a lot. (Most of all when my friend cracked up the first time someone said 'Asgardian'. I knew that would happen, and I still laughed.) It was a tad on the long side, methought, but it was very together. The only thing I was left missing was more on Hawkeye - there was precious little info on him.
So on a very limited experience on superhero movies, it was good, but I feel no need to re-watch it.
Uh. No. We need a BlackHawk double feature film. At least.
And yes, DAT ASS. Straight male over here with no significant other to hurt me for saying that.
(And yes, I'm aware of all the crap female actors go through, and I don't agree with it—neither does Joss or Scarlett, but they recognize its place in American movie culture and did it anyway, despite their misgivings.)
I think my favorite scene was...nevermind, that's the whole movie.
Yeah, the only other villian I can think of who's made it to three films is Magnito in the first 3 X-men. But supposedly Loki isn't the main villian in Thor 2.
And yes, a film with Black Widow and Hawkeye jointly would also be tasty. However! Whedon can't write/direct that film, because then either the relationship will be even more disfunctional than it already is or one of the two will eventually die a tragic death.
