I don't see many French movies, but the ones I do end up seeing are usually critically acclaimed ones such as this one. In this case, I think it's well-deserved, as it's one of those comedies that couples cunning and intelligent humour with deep and heartfelt emotion. The humour itself never lets up, possibly even becoming better near the end of the movie (a rare feat), yet always staying relevant to the story and well-acted. It's most definitely worth watching and is a great little movie.
In a sentence:
Smart, funny, heartfelt and supported by solid acting and production values.
