I don't often agree with Naomi, but I also don't wish to be made to feel emotional in the way that mass-appeal shows like this do.
If I wanted back stories, I am sure the media will produce them, for a long back story to accompany one act is an unfair advantage, people are voting for the tragedy affecting one member, not the talent of the troupe as a whole, which is unfair to both, and to everyone else on the show.
I am going to have to stop watching this show - David Walliams' creepy on-going campathon is really getting on my wick.
It's only the stratospheric beauty of Alisha Dixon that keeps me viewing at all!
