I wasn't really blown away by this book -- and to be honest, I wasn't expected to be either. I knew even before I read the synopsis of this book that it was an obvious money grab by J.K. Rowling that doesn't really need to exist and, well, I think I was right. It doesn't need to exist -- it doesn't really add much to the Harry Potter universe and it felt more like a fanfiction then a true Harry Potter story. That isn't to say that I didn't enjoy reading this to some degree -- I did, but it is obviously a bit disappointing compared to the other books in the HP series. 
 I know a lot of people didn't like the script format of the story, but I actually didn't mind it at all -- I actually kind of liked it. What I didn't like, however, was... everything else. It is a decent standalone story, but I don't think it should be canon in the HP series. And, from what I see, I think many others agree with this. Another complaint I have is the forced heterosexuality of Scorpius and Albus. I'm not going to sit here and say that they should have been a couple (even though I would have definitely liked that) because I can see why they aren't -- this book is a money grab, and money grabs try to be as inoffensive as possible as not to scare away potential (homophobic) audiences. But, the forced unrequited romantic subplot between Scorpius and Rose just felt like J.K. Rowling put a huge sign over Scorpius that says "DON'T WORRY! HE'S NOT GAY! TRUST ME!". Honestly, shit like this makes me want to gag -- that subplot didn't need to exist, and the authors literally forced it in to make sure people didn't think Albus and Scorpius were gay. It's so infuriating it makes me want to cry. 
 Overall, though I just crapped all over it, the book/script was okay -- it was a quick and enjoyable enough read.
