The issue i had when i watched it when it first came out, it didn't feel like a complete movie. With all the hype about the Avengers movie coming out, it felt like more of a prequel then a stand alone film. I was left feeling unsatisfied, but now I appreciate it more. Its one of my favorite of the marvel flicks. I think it maybe its the fact that the story was so simple and concise, it didnt try to blow you away. Also it didn't rely on a bunch of CGI effects like the other ones. I feel that's the same reason Winter Soldier is gonna be one of their best films. It'll focus more on the villain and story, then trying to wow everyone with special effects like Thor and the recent Iron man Movies.
