I grew up going to the older theaters, that had just the one room and one screen, and just one movie playing. You could go in, anytime of the day, and stay long enough to watch the movie two or three times, if you wanted to. Now they won't let you in, if you're five minutes late, and they run everyone out between movies.
The sound at the theaters has always been terrible, and still is. The volume is always way louder than it needs to be. Actors whispering to each other, could be heard two blocks away, if you used the same volumes at home.
If I could afford a good projector and big screen, in my home, I'd never go to another theater.
Drive-ins were fun, during their day. You had volume control in your car. You also had some privacy in your car. The worst thing about drive-ins, was the mosquitoes(sp?) Yeah, you could use those PIC insect thingies (looked like a burner on an electric stove), but the smell of those were terrible.
