To be honest I don't know what the judges are looking for. Atleast in the olympic ice dance you know there are strict criteria (even if it's incredibly complicated!). I really haven't a clue what the criteria is in this programme!
I just have to watch this programme and decide which performance I enjoyed the most and that is how I vote.
It's hard because the props are different and the dances don't always look like they are the same degree of difficulty to me. People go out of the competition , yet they are good ice skaters. I think it's like pop idol. You will get to a stage in the competition and people will vote for their favourite. It's not always the most talented who wins.
