ThePavlovianCat - I went off him in one of the very early series, when he was competing. He came across(to me anyway) as very arrogant, and clearly thought he was far better than the others. When he was given a low mark for one of his dishes he was very sulky about it.
The new scruffy look does seem to have mellowed him a little, he used to be very harsh. He's being very free with the '10's' this year
