Despite a few fabulous moments, I got a bit bored, especially during the first part of the film. The fooleries from the rear seats bullies seemed a bit exaggerated. It's nevertheless a great concept. All characters felt genuine, and necessary. The bizarre constructions in papier-mâché and bits of string from Gondry's univers, which appear by parsimony in the story perfectly fits to the post-kid-not-yet-teen context.
