Tonight it's Harry Potter and the Cursed Child Part Two, and as with Part One of J.K Rowling, Jack Thorne and John Tiffany's story I'm going to to do a review with some degree of spoilers, a little bit spoilery for plot, a bit more so for characters and staging, as a record of my reaction for myself if nothing else. So read on if you've seen the plays already or are involved in the production and already know everything; or, I guess, if you're absolutely sure you have no intention of ever seeing it either at the Palace or when it eventually opens on Broadway and, probably, territories all around the world. If you have tickets, are planning on going to see it or there's any chance you might some day, #KeepTheSecrets and stop reading after this paragraph.
