“We cannot protect the young from harm. Pain must and will come.”
Upon completing book 7, I was among the masses who questioned the strange final chapter in the series. It was out-of-place, and written like bad fan-fiction. It didn't make any sense to finish the series in that way. After book 7, HP felt incomplete. Something was missing. And since book 3, many fans were left wondering how JK could completely ignore one glaringly obvious issue. However, HP and the Cursed Child is the true conclusion to the story.
The play tackles many unanswered questions, ties up a few loose ends, and farewells a cast of hundreds. And now that I've finished the play, I can say that I'm satisfied.
