I haven't seen Thor but my brother and a couple friends have. They all really liked it. I've also heard really great things about Captain America.
Although I haven't seen all of the Avenger movies, I saw the first newly made Hulk and didn't like it... But I LOVE the Iron Man movies. I really now Robert Downey Jr. and I think he makes a great Iron Man.
I cannot stand to even consider watching Thor, simply because the actor is a famous TV actor here in Australia and that show goes against all my principles.
I expected way more action from the Thor movie, I think they could have spent less time demonstrating what an ass he was before he was banished, and spent more time showing him kick ass as a hero. But I understand they were trying to set up the character for sequels/the Avengers, so. It was an ok movie, but it wasn't anywhere near as good as Captain America.
I enjoyed the masculinity of the Thor character and the lessons learned, he looked awesome with his shirt off, my boyfriend didn't like that one bit but, I couldn't help but notice. I want to see Captain America too, maybe I will soon....
I really liked both Thor and Captain America. I'm also a fan of Iron Man. I'm a little wary of what sort of Hulk they're going to be using for the Avengers movie but so far it's looking promising.
