Not 100 percent sure how to rate this... 
 2007: All was well 
 2016: Um, well actually... 
 I'm surprised I didn't hate this book. This wasn't a total disappointment. 
 But I definitely didn't love it :( 
 I liked that we got to see how our beloved characters were doing in the future, but no Neville or George:( 
 Plot wise it was OK, but it was going in circles at times with all the time-travelling. Did they really need to bring Voldemort back? 
 I thought the idea of play was an interesting concept at first, considering how most potter-heads have the wizarding world committed to their memory. But no. It was a terrible idea ( a bit lazy if you ask me...). One of the great things of the first 7 HP books were how rich the description was of the strange wizarding world. 
 Lower your expectations, but still give it a try.
