Don't get defensive, just because their slogan was "ride the movies" they really didn't have to actually do it.
True, Mission Space is a simulator but theres no other similar attraction like that in Orlando, or anywhere else that I know of. It exposes riders to forces up to 2.5G, more than twice the force of gravity at the Earth's surface. So the resemblance to Simpsons is barely even there.
And yea, Transformers is on a track, but uses 3d. And Spiderman uses the same tech, which I don't mind but its worth mentioning.
