"Very carefully. Two men are coming to kill you." is either very deep or a fortune cookie; possibly both. It is an episode about people, which sounds obvious until you realise how rarely shows remember to do it. About 8 minutes of it is scenes you have already watched, in case you have the memory of a goldfish. There is a new face, Paul, who walks in like they already know how this ends. This is the episode people mean when they recommend the show.
