Jason is the man people love to hate, that's why he's there. The audience are primed to boo him and are actually shocked and surprised if/when he actually says something nice or gives praise, which is quite rare. People are so used to the idea of booing him and hissing at him, they often don't even listen to what he has to say, but boo him automatically. All part of the show, and he does his pantomime villain bit to perfection. I think it was great though in this series and before when a contestant would answer back, as if to say they would not take this abuse much longer, because it enabled them to appear to be standing up for themselves. It all helps the skaters, because with milder comments, if the skating was below par, the audience at home would be less prepared to show any sympathy. The whole Jason routine was probably devised by a psychologist, but he does it so well.
