I appreciate Rowling not just because she gave us Harry, but also because she is an excellent writer--like, good at the craft as well as the inspiration. Casual Vacancy? Loved it!
I bring this up because it was pretty clear to me that she was not the wordsmith of Cursed Child, and I wish she had been. That might have bumped my rating up to 5. That said, LOVE!!!!!!! So nice to dive into a new, rich, meaningful Harry Potter story again.
