Christ on a mucky stick, what is THIS? An M&S advert featuring all of the X Factor finalists, each singing a line of When You Wish Upon A Star while a little girl screams at an old man? No no no no no NO. These things have RULES. X Factor is where the X Factor finalists live. M&S adverts are for Caroline Quentin and women running around in underwear. This is ALL WRONG. I will be buying my prawn cocktail sandwiches ELSEWHERE from now on. Disturbing.
