This movie shifts back and forth, between present, when the mother (Tilda Swinton) is trying to put her life back together, and the past horrific events that lead up to it. Her marriage and career seem on track until the birth of her son. He is on the path to being a psychopath from day one. He cries nonstop as an infant and refuses any interaction with his mother as well as any love she can muster. It is fascinating to witness the animosity between the two, and she mightily tries her best to “mother” him. I won’t disclose the end. Wonderful, wonderful acting. I found the movie absolutely fascinating.
