I thought this is an unbelievable boring movie! i heard the director can't speak french and so he left his actors tell what they wanted... Well, Valeria Bruni-Tedeschi is great, as usual but I can't say the same of other actors. They have nothing to say, especially Bruno Todeschini.
They all seem very tired, this being one of the movie plot : tired of being together, of living abroad, of their live in general; so they spend half the movie sleeping in a hotel room. After a while i felt sleepy myself...
I gave 4, because of some very beautiful scenes, including the last one.
