This is written so much better than Cursed Child (which was obvious that Rowling didn't write). I hated that one and like to pretend it doesn't exist. But Fantastic Beasts has all of Rowling's humor and writing style. I don't really like this whole screenplay thing, I'd much rather her take the time to write another book but I did enjoy reading the scenes of the movie, which I also enjoyed very much.
Enjoyable, but I want a full book by Rowling (Marauder's series please????).
