I think I'd call this a perfect gray day movie and I suggest seeing it with someone who's on your same wave length because, once it's over, you're going to want to talk about it and, perhaps, piece together the parts of the story that were merely alluded to.
Kristin Scott Thomas, in a quietly intense, brilliantly calibrated performance, plays a woman just freed after 15 years in prison for murder. Until she can establish a new life, she is to move in with the sister who never came to visit her in all those years and the sister's family--a worried husband, two young adopted daughters and the husband's father, a stroke victim who can no longer talk. Soon a parole officer who dreams of visiting the Orinoco and a university colleague of the sister, who once taught in a prison, assume key roles as well. All these characters, even the little kids, come off as exceptionally real and interesting people.
This is one of those movies that reveals itself slowly and stays with you for a long time. It plays on an emotional level that reminds me somewhat of "Under the Sand," the Charlotte Rampling movie about the woman whose husband went for a swim and was never seen again. (Odd, kind of, that both are French movies that star English actresses who've lived most of their adult lives in France.)
