Pristine only happens opening weekend though. With digital projection taking over the multiplexes, a lot of people are never going to see a print that's been running for months, or in the case of Star Wars, an entire year. Movies just don't stay in theaters that long anymore.
It's the memory of seeing those not so pristine prints, is what some of us are responding to on an almost subliminal level with PG, and now PSB.
You'd also be amazed at some of the dodgy prints the studios would use for video transfers back in the 80's. They could sort of get away with it on VHS, but it stuck out like a sore thumb on Laserdisc! ;)
