The theme of family breakdown and its long-term effects on children - here well into adulthood yet caught in a kind of adolescent funk - is given a realistic but also oddly sparky treatment in this memorable film. It is unusual in that it has two real-life brothers playing brothers in the film - both excellent, and their performances can always be relied upon to give pleasure. At the same time, the sight of Jeremie Renier hiding in a ditch near the end in a state of utter despair is not easily forgotten, he conveys the pain and confusion of the character with such force. He is the more troubled of the two, but there are also lighter moments and the film taps into a vein of humour in their banter and also in physical comedy in a game of ping pong, for instance. Isabelle Huppert is superb as the mother who is somehow impossible to categorise or judge, she evokes such a complex response. In fact we don't feel we can really judge any of the characters, which is one of the film's strengths. It deserves to be widely seen for tackling an unusual subject and somehow achieving an original, ambiguous tone.
