I still don't think it actually matters much how well the next movies do. I believe that the vast, vast majority of theme park visitors would enjoy a cool immersive environment no matter what it's based on. If we can walk into a land/attractions that are visually stunning and fun to experience, it could be based on anything/nothing. I didn't like the HP movie I saw (one was enough for me), but I love FJ. I think I would have loved the ride (perhaps more) because of the environment and technology if the theme was practically anything else as well...Peter Pan, visiting Earth in the past, flying with the Jetsons, being part of Sharknado...it really doesn't matter much imho.
