Camera angles in this show are always interesting. In the initial scene camera points down and above Dorothy and the mailman. There's a downpour and it evokes a kinetic malevolence but also like they are being watched. It's not from the perspective of either Dorothy or the mailman.
The show is full of off center close up shots that gives you a claustrophobic effect. There's a brilliant close up of the "uncles" hand grabbing Dorothy. His hand is oppressively big and the gesture is aggressive even at first assaulting.
The crib scene threw people off. I don't know why he's sleeping in the crib. Maybe there's an explanation in future episodes but Dorothy's reaction is not out of character. Her entire personality is built on denial. She wants to believe the child is real so much she's able to retrofit reality to make it happen. She feels like setting off the uncle threatens Leanne's stay in that house and a part of her realizes Leanne is necessary for her baby to exist at all.
The story however is too slow and the acting is self conscious. The only one who feels natural in the main cast is the actress who plays Leanne, and she's excellent.
