Interestingly, my son loves the old special effects. He enjoys the new Ultraman every year, but the only one he asks to rewatch again and again is Ultraman Taro. But I suppose that as he gets older, he will probably change and dislike the old effects.
My only experience with VR was when I was teaching at Toyota and one of the students asked me if I wanted to try their VR demo. They had created an old house with several floors, just so they could learn how to use the software. At first I thought it would be just like watching a video game, but I was surprised at how real it seemed to my body.
It's good we aren't close to Tokyo—I'm sure my son would want to go to this Ultraseven VR show. Glad to hear you enjoyed it.
