Seriously, we have not even gotten to explore the finished attraction and many people have nothing but negative stuff to say. We get it, you hate Frozen. I wasn't that thrilled with the movie, but if little kids like it, then just let the kids be happy. Change sucks eggs, but change happens no matter what we say. I looked at the pics of the HUB in MK. I, yes I bemoaned the destruction of trees, and landscape. Once there in January, even with walls galore, I could see where it was going and what it was going to accomplish. And guess what, I liked it.
I try not to bemoan stuff quite so much now. Disney has to change, and when they change some will like it, some won't. Can't please everyone all the time. HM didn't like the idea of the enhanced queue, but having walked it many times in January, I like it now.
Maelstrom was old, out of date, and generally unpopular. Disney had something that would draw crowds into the pavillion, so they went with it. Little girls flock to Frozen. It has been a couple of years and it is still going strong. Look at a Disney store, 1/6 of the local store is Frozen. They have a cash cow and like any smart business, they are reaping the benefits of something that is still immensly popular a few years after the theater release.
