Digital projectors have been force-fed to theaters by an industry hungry for the premium prices it can charge for 3D films. As I've been arguing for a long time, this amounts to charging you more for an inferior picture. The winners are the manufacturers of the expensive machines, and the film distributors. The hapless theaters still depend on concession sales to such a degree that a modern American theater can be described as a value-added popcorn stand.
"Value-added popcorn stand" may soon describe American schools as well.
