After waiting more than a year, I went to watch the performance at the weekend.
It was a great. A really nice sequel that was enjoyable for a Harry Potter fan myself. The location was great and the theatre was lovely, I had balcony seats but was sat in the centre and could see perfectly well. Definitely worth the £15 for each part.
The story itself was portrayed with a lot of warmth. I loved Albus and Scorpius as characters, and as a Slytherin I was happy they represented two Slythern characters as genuinely good people

idk if it comes across like this in the book, but Harry was quite unlikable throughout. A lot of the time the character would just shriek and shout; I thought there was still a sense of Harry to the character though, just not as likable or a person I rooted for like I did in the films (though this wasn't really the point anyway. Ron was fantastic, such an accurate portrayal of the character, much more than Rupert Grint playing Ron - who I find quite overrated, and after reading the books and watching the films I realised was the wrong person to play the character. Hermione was fine, her daughter was quite annoying though, ngl.
I went into the show already knowing
I feel like I would've loved it even more had I not known, but the context of which she appeared. i.e:
Yeah, the play was definitely was worth watching. Not of the same calibre of other books, like MTVN said the show is more of a gimmick than a genuine instalment, but heart-warming nonetheless.
