Its the series I enjoyed the most.
Lilia, Matthew were no longer on the show.

A lot of new things were introduced and most of them made the show better - and most of them had been suggested on this forum beforehand. And NO dance-off!
Despite removing a couple of my favourite pros, I rate Moira Ross as the best and most progressive Producer the show has had.
Celebrity performers were:-
Robbie Williams & Gary Barlow – "Shame"
Week 2: Robbie Williams – "Rock DJ"
Week 3: Peter Andre – "Defender"
Week 4: Neil Diamond – "Midnight Train to Georgia"
Week 5: Alice Cooper – "Poison" (Halloween special)
Week 6: Bryan Ferry – "You Can Dance"
Week 7: Annie Lennox – "Universal Child" & Alesha Dixon – "Radio"
Week 8: Duffy – "Well, Well, Well"
Week 9: James Blunt – "So Far Gone"
Week 10: Manic Street Preachers – "Some Kind of Nothingness"
Week 11: Take That – "The Flood" & "Back for Good"
Week 12: Paloma Faith -" Upside Down"
Matt and Aliona hopping around the country and Len being upset.
Kara and Artem - the dancing and romance and Len being upset.
Pamela and James - changed my view about older celebs.
Gavin and Katya - the unstoppable force V's the immovable object & funny.
Ann and Anton - an unlikely but good mix.
Scott and Natalie - burned brightly then burned out.
