Just tone it down a little bit.

The We And The I - 6.5/10.

I think the setting is fantastic and the idea of a city bus as a microcosm of human behavior is something I'd like to see done again, better. But Michel Gondry gets bored and feels the need to be Gondry-esque and the mix of untrained actors – while some great –  means some of the acting is not very good, and much of the movie's weight is put on one in that camp. If it had just focused on the singularity of the idea, and more time had been spent coaching the actors, it could have been great. It didn't, and so it's not.
