I listened to this as an audiobook and followed along in my physical copy (The Hogwarts Library Edition). This audiobook is so awesome! It's read by Eddie Redmayne (who plays Newt Scamander in the movie) and there are sound effects of the animals he's describing too.
The sound effects in the audiobook include the sounds that the beasts themselves make, but also when Newt Scamander beats back a beast or two with his travel teakettle. There's eggs cracking, leaves rustling, wings flapping, feet stomping...
Eddie Redmayne also reads the foreward from the book that Dumbledore has written - including telling you about a wonderful charity called Comic Relief. As he reads the book, it sounds like someone is explaining their own findings to you - not just like someone reading aloud from a book.
The 'About the Author' section is also read out as it tells you about Newt Scamander himself - his history, plus his wife and their pet Kneazles.
However, the physical book has spaces where Harry, Ron and Hermione have written in the book and the cover of the book is quite lovely.
The illustrations are really good too. Unfortunately there isn't a picture for every beast, but the ones that are there are done well.
As other people reviewing this CLEARLY don't know, this is NOT the Fantastic Beasts screenplay. This is the original book that J.K Rowling released which is the textbook that the students use. Therefore it is like an encyclopaedia of different animals in the wizarding world. It does NOT have a "story" as such. It is informative.
