For example, when I watch 6.0 programs now, I actually notice how empty a lot of them are, and how weak the spinning is too. The footwork also looks easy. So for me, I think there is some good about IJS.
Also there were some crazy results. I don't think Patrick would have won 2013 worlds under 6.0 and I do think the quality of a whole program needs to be taken into account.
Also while I think spinning in a lot of ways is better now, I must say I miss super fast and tight spins. A LOT and unique moves. Just because someone can eek out a spin, doesn't mean they should.
In terms of dance though, I miss some of the dance programs. I don't know if anyone can top K/P's 1992 Olympic free.
