>>121713The most recent movie I watched in cinemas was Dune 2, there were some nice things and bad things about that experience.
In terms of visuals, I'd say the big screen definitely did make my experience a lot nicer. I don't have any kind of "home cinema" configuration or anything like it. A big screen projector in general has always appealed to me for really pulling me into a scene visually. I watch a lot of horror movies and I thought I had pretty good tolerance for horror since I watch them at home in the dark, but the theater made these films absolutely terrifying because the shots were all so heavily imposed on me.
As for sound it's a weird mixed bag. At home, I watch movies with my really nice in-ear monitors, which do help me appreciate sound design a great deal. In theaters, the sound system is usually a coin toss as to whether or not it'll be great or just okay. What makes a good sound system for me is staging, since good staging is hard to do on in-ear monitors. Additionally, you are right, sometimes the motherfucker eating popcorn behind me needs to learn to chew softly.
The prime reason most people go to the theater though is that it's for the social reason. People rarely go to cinemas alone, they're usually with friends, going in to watch a movie that's new (or in the case of End of Evangelion) one that they've seen and already love. It's fun to sit in a theater and see your friends reacting to the same insane shit you're witnessing out of the corner of your eye.
Shit is expensive though, and piss breaks are a nightmare. So I don't go that often and just tend to torrent when I can :P
