I saw it on Friday with my dad, brother and nephew. The plot was a little lacking, but then that was to be expected. All in all I found it entertaining.
One thing really irked me though. Captain America fought some mythical, cartoonish group called HYDRA?! I think I saw one swastika in the entire film. I was expecting Captain America to do some Nazi-bashing.....and yet I saw no actual Nazi's. Ah hollywood, always politically correct, unless they're trying to bash the Tea Party.
