** spoiler alert ** 
 Well, I should start with that it wasn't a particulary bad book, but it wasn't perfect either. My rating may mirror my opinion of dramas, but - for once - this was a drama I found enjoyable. Still, I think that without seeing the play, you cannot possibly rate this five stars. I would like to see the play, though. 
 Harry turns out to be a terrible father. The first three years flow by in first 10 pages. I was hoping to see more of the old characters, or Albus's siblings, as well as Hugo and Rose. Big fat no. I was quite disappointed with that. 
 The trolley witch - I felt like it was some sort of a bad joke. Really? I get that she was lonely and no student ever asked about her name, but to actually appear on the roof of the TRAIN with her trolley to stop Albus and Scorpius? 
 On the other hand, I was quite surprised with Albus being sorted into Slytherin. He izolized himself and just talked to Scorpius Malfoy, who turned out to be complete sweetheart and he was a really good character. I didn't like how Harry (along with Ron and Hermione, and Ginny) just appeared in Hogwarts whenever they wanted to, I mean, I'm surprised that McGonagall hasn't gone mad. 
 Ron - that was a huge disappointement. He was there just to keep the humor. He was turned into a complete idiot, and I don't like it. I never liked Ron, but I have to admit that this is too much. It was like really bad fanfiction. Even my friends would keep Ron in character. 
 The time-turner plot wasn't that bad - actually, with great care it could be expanded into something awesome, but, in this case, it just didn't work. Albus ans Scorpius are just really stupid and obviously hadn't considered what they could done to the past. As a fan of science fiction I know that time can be rewritten, but something has to stay exactly how it had happened to keep things the way they should be. The two boys clearly didn't think of consequences. Even my baby cousin would know that he could change the future by that and some people wouldn't exist. That's the big mistake that forced me to go down with rating. 
 On the other hand, I enjoyed the alternate realities. It was a bad fanfiction, yes, but I loved how Hermione was like a completely different person. 
 And seriously? Voldemort has a daughter? What's more, a daughter no one knew about? I doubt it. I didn't like Delphi's character from the start, she just seemed too unnatural to me. To fake that she's Amos Diggory's niece? Oh, please. I know that with magic, you can do anything (even cheat death), but that was just... no. If Harry would talk to someone who knew Diggory 25 years ago, he would have come to know the truth before we even reached the act four. 
 I was torn between giving this two or three stars. Let's be honest, two stars are just for Scorpius and McGonagall's characters. McGonagall rocks, totally. As a headmistress of Hogwarts. I wouldn't want to be on a detention for the rest of the year :D And am I wrong, or is this the first time we learn Moaning Myrtle's full name? 
 2,5 stars. The end.
