There's not a lot to say about Diary of a Wimpy Kid: Rodrick Rules that doesn't also apply to the first film. It's more of the same of these characters: whether that's a good or bad thing is up to you. The only major difference is the decision to focus more on the relationship between Greg and Rodrick than the former's middle school life, which actually leads to some touching, if melodramatic, moments. However, it's even more disjointed and even more over the top than the predecessor, and that really hurts the film's sense of humor. Consider it a step down from the first film, but if that one entertained you, this one will likely entertain you too.
