Well that doesn't make sense to me but they're the boss. Though there's more normal bd3d discs than uhd ones.
Depends on who you ask.
Personally, I find UHD (mostly HDR) by far more interesting that this 3D playstuff.
The annoying glasses aside, with a good movie and a good plot
and if I can manage to ignore the glasses, I'll forget, that it's 3D anyway, so it might just as well have been 2D.
If I want to "enjoy" 3D, I have to concentrate on the 3D effects so hard, that I have no clue, what the movie is about (unless it's one of those simpleton movies, that are purely made to show off 3D anyway).
Watching 3D for the sake of it is interesting for a short while, but it gets boring fast - and annoying.
Add to that, that there are nearly no real 3D movies at all - for almost all of them 3D was added in post-processing, sometimes quite well sometimes not so much - it's sort of fake anyway.
3D is already on the retreat. I can see the "alternative" 2D presentations in cinemas filling up more and more, because people are slowly finding out that they want to watch the
movie, not the
3D effects.
So - again it depends on who you ask. I'm quite happy about the UHD addition and couldn't care less about 3D.
