Do you mean to suggest that the movie theater experience (projectors, screens, viewing environment) was better 40 years ago? It sounds like that's what you're suggesting.
If he isn't saying it then I most certainly will :darnkids I will qualify my observations with the usual "your mileage may vary" but my experience at local theaters, even "THX" theaters, is that they run bulbs at low brightness, audio is poorly calibrated, and projectors aren't aligned properly creating geometric distortion in the projected image. Stadium seating is fantastic I'll give you that but I rarely go to the movies any more as I have a better set-up at home.
Seeing movies like Star Wars or 2001: A Space Odyssey on a huge curved 70mm screen is an
amazing experience that was generally more available in the past (there were at least three here in Colorado Springs as well as two other 70mm flat screens all of which are long gone -- and if you were in Denver the choices were even greater).
Movie theaters today are more like large TVs than anything, IMO, and a lot of that has to do with the delivery and display systems. It is what it is, and is what the business has evolved into. Was it better back then? In my opinion, yes, but your mileage may vary.
Also, yes, there are optics that are more refined and versatile, there are film stocks that are finer grained, but this nonsense about how resolution is somehow superior in film making today needs to
stop. What has changed is our ability to reproduce the source material. Where HD, UHD, HDR, etc are important is that they are for the
consumer market and they get us incrementally closer to reproducing the source material -- the film itself. They have NOTHING to do with how films are actually produced for theatrical release. Digital film equipment in true 4K notwithstanding -- 4K is lower rez than 35mm film, which is estimated to be around 6K, there are higher resolution digital sensors but there is so much cropping and compression between what ends up "in can" vs the final product of either format it's crazy. Digital vs film as a whole different argument and I don't want to go there.
Back on topic -- @ mvmagic -- an excuse for another Vader helmet in my collection? I like the way you think ;-)
