I actually walked out of a movie a few weeks ago. The Regal theatres here have installed these 4DX motion seats. It's like sitting on an amusement park ride throughout the movie, with lots of rocking back and forth, jostling side to side, and nearly pitching you out of your seat. Then some air vent in the seat in front of us blew air and mist at us at us a couple times. All of it was supposed to mimic what was going on in the movie. And all this was during the previews.
We went to watch Mission Impossible 7, which I knew was going to be an action packed movie. I just wanted to sit with my feet propped up on one of the reclining chairs and relax. But, 5 minutes we were in those seats, I had to keep my feet firmly planted on the footrest, making sure I wouldn't be pitched forward from the seat. It was WORK to stay in the seat. They didn't have seat belts like at some rides I've been to.
So we left after those 5 minutes and exchanged the tickets for a nice "normal" viewing of Mission Impossible. Good thing, as 90% of MI is all action sequences. And it was 2.5 hours long. I don't want to work while watching a movie.

The most action I want to be doing is munching on popcorn.
Here is a video demo of the seats during a movie. You can see the little girl hanging on to the arm rest at times:
