Diana's Cranberries/Sinaed -esque vocal mannerics could be fairly entertaining with some contemporary rock material and strictly as recording artist because she doesn't have neither strength nor spot on intonation to sing live and as such she will be tiresome and unbearable beyond 10 minutes, just like Cranberries or Bell, Book And Candle were (mostly) weak live. Unfortunately she will probably be manouvered into pop record deal where she will slaughter several songs into yoddling ballads and then promptly written off by record label.
KFC or whatever their name is - that's instant write off. Louie's agency must be spending small fortune on phone revolver there is no other explanation to what they still do on the show. Blackpool pier will probably be the highlight of their career. If that.
The little boy with impossible to spell name consisting of mostly random characters. Will grow into very unattractive teenager in the next few months, in lack of voice and talent his boyish charm will be gone and he be pushed away from public eye to backstreet theatres like Haley Joel Osment and many other "cheeky freckles" kids before him. His target audience will never find him because as the press stop sending Hello magazine photographers after him no one in that age group will be able to spell his name right to google him up.
Alexandra would be the vocally worthy winner, but there is something offputting about her. Partially it's the fact that everything she does is all technique and no persona or flare - we've heard it all before, it's nothing new, you walk in to any black evangelist church anywhere in the world and you can pick two, three women singing just like her if not better. And partially it's her appearance and charisma of a background singer in a casino weekday stage act. She's very good singer, but is just bland, uninnovative and of no caliber to be a leading star. It's quite clear she thinks she could take on Whitney, bit in truth her place is in something like second lead in "Chicago".
This competition needs a rethink. Perhaps good sponsoring deal with free phone votes limited to one per number, like in Canada, to turn it back into singing competition rather than leave producers and bookies with any chance of setting bulk machine gun voting and ending up with surprises like all best bets and best singers voted out 6 weeks before competition ends.
