Ah, I can't take it anymore.
Single mother is freaking me out with her psychotic stalkerish behavior that is never quite explicitly shown.
Wife is an abusive, narcissistic, woman-child.
Husband can barely be classified as a man, allowing his wife to rule the house and never showing any ounce of investment, as illuminated by his absolute doormat nature.
I'm not gonna rag on the boy because he's a child, but he is way ahead of himself being only 13.
The only decent one is the daughter.
Everyone is stupid, this whole thing is stupid, and seems completely unrealistic (but hey, reality is stranger than fiction so what can I say, maybe it's totally realistic).
