To be clear, I enjoy reading scripts; my rating isn't an intent to "punish" this publication for not being a full-fledged novel. I would be happy to see the play and I'm sure the cast, crew, and staging are all wonderful. It's not related to who was cast in which role, or whether queer-baiting was intentional as far as Scorpius and Albus are concerned.
As far as the story goes, I can take it or leave it. It feels like quality fan-fiction. I don't regret reading it, but it doesn't enhance my experience in the Wizarding World.
