This new work of Berry is exceptional and as it's only his second, you can be sure it's a director to follow. Maybe it's because he seems to have a excellent memory or the fact that he's super-kind to cast his daughter in all his movies, but he knows exactly what is-it to be a child: a world that is high, that is not totally clear, sometimes painful and frightening but always the best time to share with your friends.
Thus, watching this movie makes you remember your old past as well because we all shared the same experiences: the love of the mother, the authority of the father, the big situation of school (mine was to keep silent the trip to Germany from my parents), the dangerous expedition (mine was to explore a vacant hospital with dead cat), the alienating vacations and family (same farm with grandparents, nothing around and silly cousins), the lessons of biology and the first beats of our heart (unfortunately, my "sarah" dumped me before our date could even exist when I just give my homework with her name on it! I have always been absent-minded if I'm troubled.).
So, Berry manages to bottle all those moments in a fresh and funny story and find an admirable cast and production to tell it: the adults and kids are really top, the sets are full of colors or have amazing light for the locations in Paris, London. The music is perfect and sounds very nostalgic.
If "Home alone" is the best about being kid and family, "Moi, César" is best about friendship among kids! Please, Josephine & Richard, go on with more movies like this !
