I quite like Halloween week so do not mind it staying (29th?) albeit a little early, but given Strictly falls on Bonfire Night this year I would quite like to have had a bonfire night themed week (bonfire heart, firework, counting stars, rocket man, disco inferno, she bangs, light my fire, spinning around, flash, eternal flame, firestarter, great balls of fire etc). With pyrotechnics galore.
I see you all eyerolling! 
The Centenary theme is a bit cack but I shall watch as usual. DWTS in the States has done TV themes twice. They did The Brady Bunch, One tree hill, Green acres, Family matters, Game of thrones tits and dragons (copyright Lovejoy!), Go! Diego Go! (eliminated), Married with children, Bewitched, The X files, Duck tales, The walking dead, Taxi and The Muppet Show.
Majority of those shoehorned routines were shite. About four passed muster.
The first time they did it, they used The Golden Girls, Gilligan's island, Mad men, Breaking bad, American bandstand, The Addams family, True Blood, The Jeffersons, Downton Abbey and The Teenage Friggin Mutant Ninja Turtles. Oje or oof as my DD says.
My point is...it could be worse than dreck.
It could be this...
