I'm sorry to be a grumbler but I really struggle to understand these shows. From the outset they are so manipulated and overhyped that any originality is lost before the show airs.
I had never heard of this Wagner character until last weekend and when I looked him up online, I struggled to see what all the fuss is about.
As for the Come Dancing phenomenon, I much preferred it whan it was on late in the evening with proper dancing and less whipping up the audience.
Then again I am probably not the target audience.
