Well, when the series starts, when the skaters are not that good, I actually tune in partly to see the skating, but actually to see and hear Jason's insults and nasty comments, and he is there DELIBERATELY to make nasty remarks to get the crowd to hiss him like a pantomime villain, and to get sympathy for the less good skaters, because you can see it both ways - okay, he is nasty and cruel, but usually when they give a poor performance, but you actually sympathise with the skaters more - now, if you had more straightforward judging and remarks, the poor skaters would get less sympathy because people would not think the judges were being too hard on them. Jason is certainly necessary in the start and middle of the series, until only the best skates remain; and after that, near the end, he actually makes nicer comments because the ice dancing is better.
