I've never been the biggest fan of 3D movies, mainly because they rarely worked for me in theaters. But watching 3D movies in VR gives a whole new life to 3D Movies.
I think it's because if I move my head, or tile my view, the 3D "sticks." It doesn't double vision, if I look a little to one side or rest my head on the headrest.
I may start getting them in 3D when I can to watch via my VR headset.
