I was really shocked by how much I liked it.
Going into the film, I had only seen Thor and the 1st Iron Man Movie.
I was impressed by how well the characters were knit together and how the necessary story lines were woven in to the narrative. It was quite seamless without getting bogged down by exposition.
Through the character's actions, you discovered who they were. Whiich is a great testament to the film IMHO.
It was funny and had the right amount of action, and thank goodness there was no shaking camera movement. (I am so over that.)
The Hulk wins out as my favorite character. Is he (The Hulk) going to get another movie with MR as The Hulk? I have never had any desire to see a Hulk film until now.
