Captain America: The First Avenger ★★½

A very pleasant first act is followed by about 40 minutes of thinking "Don't worry, this will get good once he becomes Captain America". The rest of the movie is spent slowly realizing that this is the lamest of all the avengers. Still it can be fun at times, and it builds up to the avengers in a nice way. I just wish that Joss Whedon made this one too.
