If you like this person's taste, follow her!
See it if You love the Harry Potter world (even if you read the script and hated it) & if you enjoy magical set designs and superb staging/direction
Don't see it if You don't know anything about Harry Potter, can't sit through long performances (it's a two-part play, each around 2.5 hours long).
See it if you are in the mood for a feel-good, well-told story. It completely absorbs you from start to finish.
Don't see it if You expect a big dance-type show. This is purely about the story and its characters
