The main idea of the film is brilliant, and I loved the way François (Daniel Auteuil) and Bruno (Dany Boon) get to know each other. The beginning is great and real friendship is really well depicted, but this is just a half of the movie.
Then comes the other half, which is boring and made me feel disappointed. This second half tries to be original, but it just ends what was looking like an introspective masterpiece.
