I can't see what all the fuss is about. Craig is still in the show on merit, with the possible exception of Martina Hingis, the celebs who have left were weaker dancers.
Personally, I don't think Craig is technically a million miles behind the likes of Ricky Groves, Phil Tufnell and Natalie Cassidy. Unfortunately, he is too self-conscious, obsessed with getting it right. It is like watching a reasonably talented student at your local dance studio earnestly learning the steps. Ricky G, Phil and Natalie seem able to forget the odd error and just "perform". With Craig being an actor, I find this rather strange..it should be second nature to him.
