Fantstic film on being able to mourn someone...
One of the best, most subtle on this just next to Isabel Coixet's My life without me, "Le temps qu'il reste" by François Ozon, Patrice Chéreau's "Mon frère" etc...
All the three lead actors Mélanie Laurent, Isabelle Renauld and Kad Mérad are fantastic imho.
Deeply moving.
