Query: Tilda Swinton is amazing as usual!

I liked this movie, but at times it was hard to watch. The characters have so much pain they are trying to figure out what to do with. Tilda's character is so torn between wanting to help her son and wanting to make sure he doesn't hurt anyone. She plays the part of a mother in such agony so well that it makes you agonize right along with her.This is not a light hearted movie, but the acting is incredible.
