A few years ago I built a home theater in a dedicated room. 135" screen, 3d-capable projector, etc. I built it to watch Avatar, and it succeeded very well at that. I can absolutely say that 3D worked very well in that specific instance. Saying "good 3d is hard" is very different from saying "it doesn't work and never will". I'm sad to see good 3D on the decline. When done well it's rather spectacular. Can't comment on 3d on a TV -- never done that. Avatar is the only 3D movie I can remember seeing in a commercial theater. There may have been others, but they weren't worth remembering.
