 Unfortunately, I didn't really enjoy this. It was nostalgic at first to revisit childhood favourite characters but I felt at times they just felt like an entirely new cast, their decisions and statements not matching up with who they were during the original series. In some ways you expect this - Harry, Hermione, and Ron have all grown up now after all - but sometimes it was just too separated from who they had grown to be by the seventh novel. 
 I also didn't like the choice in plot. Messing with time travel only created unnecessary plot holes in already established lore and it didn't seem the writing paid off for that sacrifice. This was likely much more entertaining on the stage and the magic was lost when reading the script alone.
