** spoiler alert ** 
 I had no intentions of reading this script. Watch the movie, what's the point, right? But I ended up in the bookstore and the person who was with me just shoved it into my hands...and well, I couldn't say no. 
 It should be read- it has JK Rowling's magic all over it. 
 There's just the name of a few creatures could've been better and didn't really fit into the rest of the Harry Potter world. For example : Obscurus and Swooping Evil ....really? That's the sort of names you give when you don't have a clue what to name them- but you were supposed to go back and fixed them up!! I just kept thinking of cameras and a black blob of gas....not really what I wanted to see. 
 There's also the whole point that these two creatures never show up in the Hogwarts trio time and it felt a bit too disconnected. Other than that I loved it and now cannot wait to see it!! 
 Those are the reasons for 3 stars on not 5.
