Scores out of 10 instead of 6, having the head judge(s) be the most respected/famous names in their particular fields ( Torvill and Dean are known worldwide, as are Len Goodman and Shirley Ballas to ballroom and latin dancers), the scoring graphics are very Strictly, and even the ‘mean’ judge sits in the same seat on both shows now (left hand side of the screen).
For years, I’ve thought of Jason Gardiner as a poor man’s Craig Revel Horwood, and with all these changes to DOI, it makes it increasingly obvious.
The producers of Strictly explained why Craig sits on the left - on the first show, he sat on the right but, because his marks were lower than everyone else's, whenever they were doing the scores they would always finish on a bit of an anti-climax. So on show two he swapped with Bruno, which means you now generally get the scores increasing as you go along and that makes it all seem that bit nicer and you end on a high note.
Craig works on Strictly because he's always the first to send himself up, in a way Jason Gardiner doesn't so he just seems pointlessly nasty.
