@Alicia has a good video on this. Yeah kinda a coaster/darkride hybrid. My thoughts are that it should be a thrilling ride. Now I know from the start Uni/Nintendo wanted a family ride. But they can dance on the knife edge of thrill and family friendly. I could be wrong but I don' think this is gong to be thrilling enough for my taste.
I hope it turns out fun and a good ride, I just think Universal has a history of underwhelming delivery on their projects. (hagrids being the exception)
