This took me six weeks to finish. That should tell you how little I enjoyed this. 
 Cursed Child is a bad fanfiction. If I had found it on a fanfiction website, I wouldn't have finished it. 
 I of course knew before hand that this was written in play format, which doesn't bother me at all. What bothers me is that it is so blatantly not written by J.K. Rowling. Which I also knew, but I wasn't anticipating just how little Jack Thorne's writing style resembles Rowling's. And nobody writes Harry Potter like J.K. 
 Secondly, the characterization made me want to vomit. Granted, the script is just the skeleton of the play. We're not getting to experience the actors doing their jobs on the West End and bringing these 2D characters into 3D. But still. Thorne reduced the characters to one personality trait. And the things they said and the way they spoke to each other is not how they each spoke in the books or even the movies for god's sake. 
 Thirdly, the plot. UGH so bad! Even though this is a fictional world with fictional people, some of the things that happen in this play JUST WOULDN'T HAPPEN! Without revealing any spoilers, some of the plot points were soooo fanfictiony and made no sense whatsoever. I get the sense that Jack Thorne has maybe seen some of the movies, but has never picked up a Harry Potter book in his life. Scorpius Malfoy was the only good thing to come out of this story. 
 If you're a fan and you've hesitated to read this play: DON'T. If you want to experience Cursed Child I would recommend buying a ticket to see the play live. It's clear from the stage directions that the costumes, set, sound/music, and stage magic are spectacular! Maybe the design and acting are so good it'll distract you from how bad this play is.
