Totally agree with @kayak.
Affable French comedies are a guilty pleasure and this hit the spot.
My only real gripe would be surrounding the birth of the daughter. There is no way he wouldn't have had a call at least from her parents to say it was happening and the duration of the pre-waters, "clinic", birth was entirely unrealistic to the point it bounced me out of the reality of the film. A minor gripe and a forgivable crux of a minor plot point in context.
The highlight was the pair as faux-Japanese at the molecular restaurant. I nearly choked on my laughter seeing "Leon" in that get up.
I am a huge fan of Jean Reno and enjoyed his work here. Michal Youn was extremely well cast though I kept feeling the films make up artist was hitting him too much in the face with the powder.
I would recommend it as a light entre to Chef (http://trakt.tv/movie/chef-2014) with a desert of my favourite Pixar film, Ratatouille (http://trakt.tv/movie/ratatouille-2007).
Typical French comedy.
Ratatouille in real.
Light and delicious.
