Love love love her, she made someone who wasn't having a very pleasant day crack a smile with all that positvity. She reminds me of Pollyanna in the film with her "glad game" Jean to me is a human form of the glad game.
I've just watched Jean's audition and performance and she's brilliant and I'm glad she's through to the final. I'm fed up of people moaning about her facial expressions and the way she acts while playing - that's her style and I like it.
