Our Darkening Film Screens

Roger Ebert on the literal darkening of American movie theaters due to 3-D.

I know Ebert hates 3-D with deep passion, which I more or less agree with even though I could see theoretical artistic advantages to the technology. But the fact that these projectors simply don't project 2-D light effectively is an enormous problem. No doubt the public won't care, or if they do, it'll be to demand more 3-D. Will art theaters soon become known for showing films at full light?
