French films are characterized by dialog and this film is no exception. The setting is clever - not really a modern adaptation of The VIP's, but on that order (and more down to earth). The situation is funny and, in the cell phone era, one to which we might all relate. (Of course, I assume not many people lose their cell phones à la Juliette Binoche.)
A fan of both Binoche and Reno, I find both charming and the chemistry between them very real. Binoche's beautician is also far more interesting, and less stereotypified, than American film portrayals (Fran Drescher, Dolly Parton, Jennifer Coolidge...)
Not one of the great French films by any means, but I still give this one 8/10.
