I too am excited, but wary based on a couple of things. The last two live musicals were terrible IMO and some of the costume and set stuff in the special seemed a bit fake and cheesy. However the nature of this show benefits from the bright spectacle. It's pretty inherent that it is a fantasy world so they can get away with it a touch more. Not sure how the whole of the production elements will translate to film. Love the LED screens though. Think that is a brilliant choice for a filmed live event.
However I was very impressed with most of the rehearsal footage, the singing and dancing aspects. Shanice Williams is lovely. And the whole cast is fabulous.
