I'm happy with the events that require judges. It's not
that subjective. There are very clear rules where points have to be awarded or taken away. And as long as the judges are impartial (which they generally seem to be these days) they are very consistent.
The expert pundit in the diving commentary (whoever he is) seems to be able to very accurately predict the scores the divers will get before they have been announced. Same with the gymnastics lot.
It's not like judging a piece of music where one person might love it and another might think it shit house. Either you nail a triple back somersult or you don't and points are awarded accordingly.
As for other events (notice my deliberate non-use of the word "sport"
) I don't think it's really my place to say they shouldn't be in the games just because I don't have any interest in them. Plenty of other people do, so that's fine. I don't really care if they bring in tiddlywinks or wanking to be honest...
