I'm actually kind of shocked at the online reactions (here and other places) to this announcement. I kind of felt like "Potter is over" for so many people between the generation who grew up with Harry being older now and just aging out, and the whole JKR backlash of the past few years, but there seems to be a lot of genuine excitement over this.
I'll admit this was my least anticipated announce since I felt like "yeah, more Potter. I'm sure it will be good, but I just don't care that much anymore", but I was impressed by the "life" in those Paris streets which is not as obvious when you look at the grey/white buildings. They managed to make it feel as alive and interesting as Hogsmeade and Diagon.
I am kind of surprised how many people in the "theme park community" seem to be surprised by the stuff announced since
@Alicia has been laying it all out for the whole world for a while now.
