It's a fad I'm sorry to see go. I bought a Sony Bravia passive 3D TV as doctored ordered. One of my daughters has focusing problems and focusing on 3D really helps with the therapy. When I bought three years ago Netflix had 3D titles; no more. I always buy 3D in movies I like, but not many are making them. I will continue to pay extra for the DVD, and it's worth it. Usually, you get 3D, Blu Ray, regular DVD, and digital copy all in one.
My fear is my Sony passive 3D dies and I'll have no replacement.
