I understand opinions vary, however...
The average polyester high speed dupe print the vast majority of people have seen for a number of years now is just above 720p in digital terms as far as resolution and color balance can vary widely from batch to batch. That's when it's new. The degradation of the element begins with the first pass through the gate of the projector. A projector that could be 25 years old, or more, and of questionable condition. many (most?) of them run by the same guy that also scoops up your overpriced popcorn.
Obviously digital is not a perfect medium either, but if any group would understand the inherent advantages of a digital system in movie presentation, I would expect that here.
Every screen in every theater gets the same digital video file that is a virtual duplicate of the master that the filmmakers created. While there is some variation in digital projectors, it is nowhere near that of film projection. The local theaters I frequent have been all digital since last year, with my main location having been all digital since it was built several years ago. This location also added two digital IMAX screens in the past year. I recently saw my first digital IMAX presentation when I got out to see Ghost Protocol. I was stunned. And this was in the last weekend the movie was running. Of course it looked as good as opening night.
No more film projection at the local cineplex?
I will shed no tears.
