It plays out like a Gallic version of The Trip, the sitcom starring Steve Coogan and Rob Brydon, but with fewer gags.

The colour palette of bleached bone whites and brilliant blues, and the haunting music of Charles Ives add to the odd, mesmerising atmosphere.

Promises much, but ends up feeling strangely underpowered and insincere.

The movie builds to a surprisingly straightforward jab at the emotional solar plexus, which worked for me.
