Murder charge

Kristin Scott Thomas is haunting in I've loved you so long. She plays a woman who gets out of prison after 15 years for a murder. The film is all Kristin even though she does not say much, but the lighting of her cigarette just stays with you. She's killed her six year old child, you realize along the way, and she's remorseless. You figure the whys in the end, so it's a must watch!
I loved the way the film built up though I didn't like the climax. The performance was excellent but I could not buy into the veracity of the last 15 minutes. It somehow robbed the film of its essence!
