I totally get wanting to see a movie on the big screen. A lot depends on one's sociability. While being a certified misanthrope, there are social scenes that I will tolerate - meeting friends for drinks and whatnot, as long as the gatherings are small.
The one place where my misanthropy really kicks in is when I'm watching a movie or TV. Even sitting in the house with family or friends, I CANNOT STAND people talking or making noise and making me miss stuff. I want absolute silence and will sacrifice the really big screen* to get it. I realize that's my own foible and that other people are "more normal" in this regard. :)
*Though I find that I like the viewing and sound experience I get with my home setup over the theater screen, and with the TVs coming out now, it makes it (in my opinion) much more feasible to get the theater experience.
I get the talking thing. After my Army time, and a year spent as an intake prosecutor, I developed the ability to completely tune out an entire conversation and listen to something else. Wife hates it, because she'll have TV on, and if I'm reading, I'll have no idea what's happening on TV. Some can happen if I'm watching TV and she tries talking to me.
On the home theater, if I could do what I'd want to do, and build a devoted theater in the basement, I'd be fine. Big TV, sound system, dark walls, good seating, fridge for beverages... Maybe after the kids are off at school...
