I enjoyed Captain America: The First Avenger a lot. I was not sure going into it that I would like it because the initial reviews were not that stellar, but it really was quite entertaining. I would not say it was the best movie of the summer, but it is definitely worth seeing.
There are a few spoilers here, so I advise you to proceed with caution.
The first thing that stood out to me in the movie was that it was funnier than I expected it to be. There is very little humor in any of the trailers, but there is a lot of humor in the film. I am not saying it is a comedy, but there are some great one liners. I do not know why I was so surprised by this, but I was, and I it was one of the things that made me like this film as much as I did.
