I agree this was a fantastic show, and I'm really looking forward to the rest of the series.
Did anyone else feel sorry for Joe Powers? I didn't think he was a con-man - just highly deluded. His whole identity is so invested in being "psychic" that he doesn't even notice the obvious deceptions he perpetrates upon himself (he saw the girl's Mini, his sister told him stuff about her neighbour etc). He reacts with angry defensiveness to anything that might expose these deceptions because it threatens his sense of self.
