Excerpt from Movies to Television
by: P. Kael

"He fell in love with his baby-sitter, so he remains a baby. He's unusually polite and intelligent, but in a mechanical way - just going through the motions, without interest. He gives the impression that he wants to withdraw from this human interference and get back to real life - the box. He is like a prisoner who has everything he wants in prison and is content to stay there".
