I mean...it's not terrible, but Cursed Child just doesn't live up to the rest of HP. I'm not sure how it could, and I kind of wish JKR could've just left the epilogue where it was. That being said, it does exist, it seems promising, and I wish I could see it. The plot has some iffy parts, but they might work out onstage?? I haven't given up yet. Alas, I live way too far away to ever see it.
