Lauren was my favourite, and after she left, I wanted Sophie to win. However, Danielle is absolutely fantastic, and will grow into being a fantastic Dorothy within the next year. She is the best actress of the three, and looks really pretty. I thought her reprise of Mambo was even better than the first time she performed it, and it might be my fave performance of the whole series. I liked the first part of her 'Over The Rainbow' but to be honest, she was awful in the last part. She couldn't even hit the last note (and some of the ones leading up to it). You might think she wants to keep it small and subtle, but to be honest, she could NOT hit those notes. And it is something that we've seen that in all her other performances. It might work ok in the stage show if she does it without singing the high parts, but as the finale to the programme, it was a HUGE letdown that she didn't do it.
But as ALW said, a lot of vocal training will hopefully sort it out for her. I'm surprised Charlotte or any of the others didn't pick up on it. But she still totally deserves to be Dorothy, and I will be looking forward to following her career.
