I wouldn't put too much stock in the review score. The reviewer has been incredibly harsh on this episode because he didn't pick up on a few plot points that were abundantly clear to everyone else that was paying attention.

Spot on. I honestly thought the opening was a half hearted attempt at satire and expected a canned "Whooooooooo!" from the audience when Shirley entered.

Was hoping he would whisper "It's a kind of magic" in Charlie's ear before plunging in the knife.
