Just watched it. It's basically the same as the first one but with even more references and in jokes crammed in. The hartfelt core to the movie isn't as good as the first. However it serves it's purpose as the foundation in which to lay all your action comedy. If jokes about a certain comic book artist's inability to draw feet makes you laugh you will love this. Otherwise.... eh it's an ok ride even if you don't know why all the nerds suddenly started laughing.
