Simulators like BTTF, Star Wars, and the Polar Bear exhibit at SWF trick your brain into thinking it is going a direction it is not. This makes me sick and out of it for an hour after riding one. Yet I'm the biggest coaster fan on the planet. I can also ride Gravatrons, and had no problem with MS at Epcot. But I won't ride simulators ever again.
This ride is bad because it shakes violently. If you are in the back row, watch out for your head. People have been complaining, yet the park has done nothing to change the ride program. All they need to do is tame it down, and make the car do gentle curves that match the movie. Instead, it shakes back and forth, like they're trying to prove something. You win, you win, I'll never ride again.
