Well, I watched it last night, and I just fell in love with Robert. What a brave, bright, resilient kid.
Taking him away from his grandmother was a good thing. Even though Robanna seemed to be lacking somewhat in her parenting skills, it seemed to be more a result of low self-esteem than anything else. Once she got the kids back, it seemed she was doing the best she could. The scenes of her playing with the kids towards the end were so sweet - she really seemed to enjoy having them with her. You could see the love that was there.
The school principal was such a caring woman. I felt her frustration when she was speaking with Robert's grandmother. I do agree that she was causing most of his symptoms and that the whole thing was a self-fulfilling prophecy. She would make him mad, physically restrain him and say, "Let it all out," as though the anger wasn't caused by her! The psychologist's assertion that it was similar to Munchausen's syndrome by proxy seemed pretty accurate to me.
I would love to see an update at some point. I know I'm going to be thinking about Robert for quite a while after seeing this program.
