I saw an article (Time online, I think) hashing out how poorly home adoption of 3D has gone. If home 3D never gets fully accepted by the public it'll be more than just having to use glasses that killed it. When 3D software was becoming available, the industry did everything it could to discourage the public.
First, you've got the "You want Avatar? Sure just buy a Panasonic TV!" The killer app comes out for 3D and you limit who can have it? And they continued to do this with other titles, but Avatar was the biggie.
Than there's the absurd price premium for 3D titles. This has gotten a little better, but there is still too much of a premium for 3D titles. I remember when they were charging over $30 for Harold and Kumar (I didn't pay that). You'd have to be smoking something to pay that much for that movie.
You can't introduce a new technology and hope to have the GENERAL public adopt it, if you market it like it's only for early adopters who will jump thru hoops and pay any price. Make it GENERAL public friendly, please.
And filmmakers, start getting a little brave with your 3D. Don't overdo it, but poke my eyes out a little, would ya?
