What appears at first to be the French female answer - in director and in main cast - to the 400 Blows (and to an extent too Small Change, which came out the year before this) - ends up having deeper levels if only because a) there are two sisters here, and the structure of this definitely and umabashedly episodic film is split by the younger one in the first half and then more the older in the second (they're only age different by two years but, one thing this filmmaker knows well and wisely, when you're young those two years matter a great deal), and b) it's more politcal and sociolgically a buzz.
If nothing else there are moments the director stops - amid the many, many of lifes little moments - for a side character to have a monologue or reveal something (ie the girl detailing a massacre she witnessed) that keep it humming with drama amid the lightness and comedy. It's a movie with men who seem threatening and welcoming, perversity is around the corner, but innocence is maintaned despite everything.
It's a playful, dark, sad, delightful, startling, and full of wisdom. The girl actresses are natural and convincing, even when they have to cry or act besotten or whathaveyou. The drawback overall is it's all too long. But hey, better to have too much than too little.
