Two reasons I watched this movie: I’ve read the books the movie is based on and it was free at the library. Two quick thoughts on the film:
1. The books are much better. There was a clever character to the books whereas the movie was just another fairly formulaic kids movie. The books often made me laugh out loud while the movie did not.
2. There is a genre of high school movies – this could be considered “high school movie lite.” It had similar themes including what it means to be cool and dealing with family members and featured plenty of pop/rock music. There were typical characters including the overly-machismo gym teacher and the older goons. If you have seen an average middle school movie, you’ll feel like you’ve seen most of this movie before. It just so happened that the main characters were younger.
Overall: read the books for the real Greg Heffley.
(The film got mixed reviews from critics: it is 53% fresh, 40 fresh out of 75 reviews, at RottenTomatoes.com.)
