I wonder how much of that uncanny value would simply be due to the unfamiliarity of the technology. For example, I'm sure we all know about the stories of people freaking out when they saw http://en.wikipedia.org/wiki/L'Arriv%C3%A9e_d'un_train_en_ga... though there's some doubt as to whether or not they actually ran to the back of the room. Either way, my point is that I'm sure all new technologies at first seem either unnaturally boring or unnaturally exciting. Eventually, people get used to them and that effect wears off. At this point, I think the only real obstacles standing in the way of widespread VR adoption are the possibility of motion sickness and the resolution of the displays (screen door effect). Otherwise, it seems like the tech has matured and would be very useful to a lot of people.
