I've gotta say that this was one case where the movie was better then the book! The way they changed the focus of the story to be on the two brothers, Greg and Rodrick, forming a brotherly bond over time was definitely a plot point that was done MUCH better in the movie that wasn't even existent in the book. The plot just felt much more real and down to earth to me. Not to mention that the movie was perfectly cast, with a stand-out performance by Devon Bostick as Rodrick. However, the rest of the cast did a spectacular job of playing their parts and making their characters feel real. Another note-worthy detail that needs to be pointed out is that the set design and the locations that were used in the film were fantastic and were a great fit for the type of movie this was. Though it does have some small flaws, I would still say that this is a great movie, probably the best in the Diary of a Wimpy Kid series, that you should watch.
