I agree that the compulsory elements should be reintroduced, and drawn to our attention, so that the judges are marking on technical stuff and not just their impressions/bias.
As for who should be on the judging panel, I am fine with Robin and Jason continuing, but it seems a bit odd that Karen is a judge as well as a coach, as she will, inevitably, end up biassed. I didn't know that she and Chris Dean were an item, but I don't think that makes any difference to whether she could be a judge.
It may be better if she stays as a coach, and is wheeled out on other programmes to talk about how the celebrities are getting on in training, and hand the judging to someone else.
Please not Louie Spence - he was unbearable.
I do like the idea of one of the panel being a previous winner - that worked on SCD, and could work on this, if they can persuade any of them - and I like the idea of one of the panel being a non-skater. I actually think that Ashley was fine for that, if only it had been balanced by the other judges talking about technical stuff more, which didn't happen nearly enough.
