I don't care who won as long as it wasn't Rydian.
First of all he already had auditioned for the show Any dream will do, he has had classical training (Leon had no training). In his audition he was a right arrogant pig, even Danni and Sharon thought he was awful.He was so full of himself then all of a sudden when it went to live shows he turned into a normal human being (someone obviously had a quiet word in his ear).
Also one more point, he seemed to play it all very nicely, saying he was happy for Leon etc, but on the extra factor, when Fearne showed him his best bits, he seemed to be "having a go" at Danni Minogue, to the point were they actually removed the small screen from the bottom (showing his reaction to the clips).
Rydian really thought it was in the bag and he was definately going to win...for that fact alone i am soooo GLAD that Leon won, at least he is a nice young, sensible, sensitive person.
