Well, I'm not really sure I agree with this because after one episode we don't know whether Peter is actually having incestuous desires about Pru (I suspect he is, but its not as obvious as the original, which really made it pretty clear right from the first scene) We don't know why Pru is with Gavin. We don't know why Peter has started an affair with Sarah. We don't why Gavin is violent.
So really the jury is still out as to whether, ultimately, the behaviour of the characters will make sense or not.
