This movie features a good performance from Tilda Swinton, as well as John C. Reilly; however, the film itself is all style and no substance. It does nothing to delve into the mother/son relationship that is at the its core, instead choosing to wallow in misery for misery's sake. The movie never presented any real reasons for the boy to turn out the way he did, instead it presented him as pure evil from the start. The actions of the boy and his parents just didn't jive with reality. This type of story belongs in campy horror flicks, not (what seamed to be an attempt at) a realistic look at the devastation suffered by the mother of the perpetrator of a high school massacre. In no way was this film entertaining (unless you appreciate the feeling of dread), nor was any aspect of it redeeming or meaningful upon reflection.
