I hope one day we are able to simply walk/drive/fly around the worlds created for movies like Monsters, Inc., Secret Life of Pets, Luca, Turning Red, etc. The artists and modellers have done such a fabulous job of creating these insanely detailed worlds, and I would love to be able to actually explore them at my own pace. For me, this would be a great use of VR, though I think we're probably at least several years away from having the hardware necessary to render that all in real-time at a quality that I'm hoping for.
