It's good that she's a Harry Potter fan like us. That's how I know she'll do the role justice.
I feel happy for everyone who will be able to see the Cursed Child when it comes out. Sadly I won't be able to see it since I'm in Minnesota (but I really, really, really, want to :p) but I'm happy that the script version (which is over 300 pages) will be available for us. I really hope they make it into a movie too because that would be AWESOME.
