I think Gary Goddard said in a podcast last year that in the newer 3D rides since Spiderman, the pacing or the storytelling is off. He didn't say explicitly, but I think he might have been referring directly to Gringotts, because he said too often in the new rides the vehicle stops, and it feels like the ride is start/stop, start/stop, too much to be fun or even tell a cohesive story.
