You just have to have the right gear and a few people to put you in motion with a good aesthetic and the film will take care of itself.
When you start to see things that are well-executed you'll watch a lot of stuff in 3D and see the same scene again in 2D and realize, "Oh, my god, it's like you turned the color off or the sound off." Once you get used to it, I think audiences and the public will want more of it.
Even if you enjoy the activity of exploring caves, to be trapped and not know whether you're going to get out alive is terrifying.
