If I can replicate the experience to a good approximation in my house why would I bother going to a theater and paying a lot of money? Big screen? Got it. Popcorn? Check. Dark room? No problem. Good sound? Probably better than most theaters. What is he really offering me that I don't already have? Give me something more if you want me to make the extra effort to go to a theater.
Oh please, you're ridiculous. Theaters offer many valuable features you simply cannot easily get at home. Here's a few:
* teenagers using cellphones
* screaming kids (esp. in R-rated movies)
* people talking about the movie
* people talking *to* the movie
* arguments between patrons
* patrons shooting each other
Going to a movie at a theater isn't about technical specs, it's about the people there, who you get to have a shared viewing experience with. That's what's so special about going to a theater, and why you can't replicate it at home. At home, it's just a dry, inhuman experience with only you there alone, or maybe 1 or 2 other people. At a theater, you have a whole room full of wonderful people to share that experience with, along with all the other great things that come with being around other humans, including the talking, screaming kids, use of cellphones with bright screens, and shootings.
