Boys aged eight and over may be familiar with Rafe Katchadorian and his creative troublemaking, and according to my 10-year-old this is a pretty faithful adaptation of the books. The target market should be happy enough.
Others will find Middle School doesn't stand out from other quirky American high-school-based books that have become movies - Diary of a Wimpy Kid comes to mind. It's a big budget version of an American high-school sitcom - filled with kooky teachers and sane kids (mostly) going through the motions to survive their school years.
Rafe Katchadorian (Gluck) is a kid who struggles more than most with the discipline of school. It's been a rough few years for Rafe, his precocious sister (Nisenson) and lovely Mum (Graham); which have also seen Rafe kicked out of several schools.
To help deal with his problems, Rafe retreats into his sketchbook, drawing characters and creating stories - many of which come delightfully to life in animation throughout the film. Drawing is an important part of his life, so when the new principal (Andy Daly) dissolves Rafe's sketchbook in acid, he retaliates by breaking as many of his tyrant principal's rules as possible.
