I'm honestly not sure how I feel about it. In terms of access to content, I dislike the idea in a way. I want to love it, but JKR is all about inclusion--we've all gone to Hogwarts together, etc. And theatre can be very exclusive. I am lucky enough to be able to travel to NYC every few years to see a show, but even then, it's difficult to pull off, and I imagine tickets to these plays will be in high demand. At the same time I don't begrudge her wanting to try something in this medium; it's her right and she doesn't owe me anything in that sense. And perhaps I'm a hypocrite, since I fully enjoyed the Wizarding World, and there are tons of people who are unable to go to it. On the other hand, the Wizarding World doesn't really create new content and add to the overall HP story. So... hmm. Not sure.

Another part of me is always worried that adding MORE content to my favorite things will ruin it. Kind of like how even big fans of Star Wars tore apart the newer films (and in that case, I think the new-new films can only help). If the content is great, I'm all for it. If I don't like the content much... well, I don't know. I'm just always afraid my beloved HP will be tainted somehow. :)
