I didn't want to go watch this one. I do like French comedies but only when they are whimsical or about minorities, not when they are about typical aspects of French life like — in this case — summer camps.
Well, I am happy I did not resist the wife :-)
Although the story of the film was quite unimaginative (shit happens during a summer camp; well, everybody's who's ever been to one knows that!), the acting was good and, more important, the rythm was perfect. There was always something happening and the situations, although, again, inspired by real-life events that everyone has witnessed, were very funny.
Recommended watching if you need a morale boost.
