First of all, I love Robin Wright. She's a very refreshing actor, and she's aged wonderfully. My friend recommended this series, and I must say, it was well done. So well done that I was creeped out thoroughly by the girlfriend character (a testament to her acting). People are waffling on who the villain is, but in my book, it's clearly the gf. She'd deliberately brought harm to multiple people who hurt her, and she was relentless at it. I gave it four stars because the last episode is too far-fetched. Would a son truly kill his mother? I think not. And, boy did he come out of that drug-induced spell quickly enough to do so. Poor writing.
