Darcey I really liked at first but even though she (sometimes) knows what she is on about, she is biased and has a bit of spite in her. I think she is there to pull faces at Craig when he gives people like Ed Balls 2 points. She is biased towards guys. Unless they look like Ed or Dave Myers that is.
Bruno is way over the top with his windmilling arms and arsing about. Enthusiasm is fine but the saying is, what, you are a good act but on for too long? He is quite positive though and constructive with his criticism but sometimes overmarks.
Len is hot and cold, and his rictus grin reminds me of the Joker on acid, or a panto villain. I am fed up of the Seveeeeeen and From Len a 10, it's as old as the soggy bottom joke (that wasn't funny to start with) with whiskers on. I think he is petulant.
Craig is my fave funnily enough, because he is mean with the marks (I think Ed Balls as crap as he is deserved more than 2 sometimes) but his comments are genuine, spot on and I think his comments mean more than all the others.
