Tonny S. pointed me toward the new video of "Invincible" by the band Muse. It's a long dark ride in the vein of It's a Small World, though decidedly more violent than the usual Disney ride.
Tonny points out, and I agree, that it's sad Disney can't make dark rides any more, or at least not as often as movie rides.
Here's the video: http://bookish85.vox.com/library/video/6a00cd9700115b4cd500d09e5cad12be2b.html
