** spoiler alert ** 
 The condensed version: I loved some of it, I cried, I cringed, I'm happy we got this but I'm counting it as it's own Canon and ending the books at book 7 in my mind- 4.7/5 
 Okay so first off the real question here, is it Canon? I'm going to go with it is its own Canon. It's not an eighth book it's a script and in being a script it was amazing. 
 Lets be real do we really need world building for this amazing series? We have 8 movies, most of us have read the books at least twice, we know the rooms, we know where in the world we are, we know what's happening and the tournaments, what Godricks hallows looks like. The Harry Potter world is THAT well done details and world building are no longer needed. 
 The thing that impacts reading a script, any script is you don't get the little nuances that change a sentence, you don't get "Harry scrunched his eyebrows together in confusion" to help set up the emotions of the sentence, this is provided by the actors and actresses when they are performing. In reading this I couldn't warm up to Harry Potter as a father and Albus didn't gain much, if any sympathy from me. I do believe that seeing the play will fix these problems as I said ITS A SCRIPT so I expected this. 
 The Story: 
 I loved some and hated some. It's like JK read our crackpot theories and fan fiction and turned it cannon which is cool but weird. 
 It was weird seeing my favourite characters as adults but also amazing. Hermione is the minister! Ron's running the joke shop, this was heart breaking and heart warming, the world with Voldemort as the dark lord was terrifying and terrific(in a really scary way). I always wondered what Voldemort would have done and who would have survived still fighting and who would had defected and flocked to Voldy. 
 Umbridge as headmaster scared the daylights out of me! Scorpius as ''The King" torturing muggles and mudbloods was horrifying, I just wanted to squeeze him and cover his eyes from the awful. The moment between Draco and his son in this alternate reality was beautiful and I love Draco's character so much, he's a wonderful Dad even if he is a bit stand offish, he tries. 
 "Most of the time, I think you have to make a choice--at a certain point--of the man you want to be. And I will tell you at that time you need a parent or a friend. And if you've learnt to hate your parent by then and you have no friends...then you're all alone. And being alone--that's so hard." 
 Hermione is still a complete badass like we know she would always be there was no question there, Ron is the ever faithful idiot who doesn't share his feelings, and then we have 
 Snape, Snape, Snape. 
 I cried guys, I did, I teared up as soon as Scrorpius said it was a honor to meet him. Teared up with a sad happiness to see him working with Hermione and still being a sass master calling her a "competent student". When he was told he died and accepted it for what it was and was still his usual self "at least it was the dark lord" and the "I'd rather that then be married to him" 
 When Hermione and Ron kiss and have their souls sucked by dementors, when Snape sacrifices him self AGAIN for Lily and the cause, we see Snape's Doe patronis, he helps to save Harry and was the hero we all wanted more of. 
 "SCORPIUS: A doe? Lily's Patronus. SNAPE: Strange, isn't it? What comes from within." 
 Scorpius is a darling with Rose, a bookworm like a Hermione. Scorpius is clever, smart, lonely, and the thing I love most about these characters, he's a great friend. 
 "When Rose came up to me today in Potions and called me Bread Head I almost hugged her. No, there's no almost about it, I actually tried to hug her, and then she kicked me in the shin." 
 Albus annoyed me at times, he was silly, arrogant and made rash stupid decisions. I mean saving Cedric?! Have you not read the history books? So many things happen because of Cedric, your freaking father wouldn't have passed the 2nd task or the 3rd if Cedric wasn't there I mean C'mon some common sense please? Even just a drop? 
 Some strange things 
 The Trolley witch? What even was that and I wonder what Fred and George did when faced down with her XD 
 Hermione being a mean teacher? I can see strict but never mean, I don't accept that she wouldn't still be minister of magic if she didn't marry Ron or that she'd let it get to her, Hermione is take charge and wouldn't let un requited love get in the way of things that mattered. For gods sake she made herself an orphan to save the world! 
 Dumbledoors painting crying and sobbing? I'm sorry I just can't picture heh it. I mean I'm sure in the play you actually see it happen but I can't picture Dumbledoor crying at all, he did what needed to be done even if he was a dick to Harry at times, Harry needed to figure stuff out on his own so he could accept his eventual death.. right? 
 Beletrix and Voldy getting it on while Voldy was creepy red-eyed, long-fingered, no-nosed monster. Ok I guess I could picture that (even if I want to wash my brain with soap now) BUT giving birth before the Battle? I don't know why but I just imagined her popping Delphi out, leaving her in a house or muggle hospital and then apperating back to the battles at Hogwarts and going on a killing spree. I mean I realise now that Delphi was born "around" the time of the battle and that could mean 2 years before or whatever but still I didn't expect it to be hers and present time Voldy I thought it would be Voldy before he killed James and Lily Potter. 
 Final Thoughts: 
 CAN THE PLAY COME TO AUSTRALIA ASAP LIKE NOW PLEASSEEE IM GOING I DON'T EVEN CARE IF I HAVE TO CATCH A PLANE TO ANOTHER STATE IM SEEING THIS PLAY.
