I feel mostly the same way, but to be fair, I do have to point out that there are some (not many) cinemas which are actually pretty nice to go to. They're usually called "dinner theaters"; they cater to adults only, they serve alcohol and full meals, and you sit at tables and watch the movie. You have a button you can press to summon a server. The one I went to a couple of times was run by AMC if I recall correctly.
I also hear good things about Alamo Drafthouse, which I think is similar.
Of course, these things aren't that common, and are entirely regional (Alamo Drafthouse is only in a few cities I think).
Of course, they're not perfect, and have the following problems: 1) tickets are pricey (slightly more than normal theaters usually, but they get more profit from the food and drinks anyway, the meals aren't cheap), 2) there's no pause or rewind, like with any theater.
Personally, I'd rather just stay at home and watch a movie. I can sit in my recliner, I can eat or drink whatever I want (and it's as cheap as I can buy it for at the grocery store), I can pause to go to the bathroom, I can rewind if I miss something or don't understand something, I can turn on subtitles if someone has a thick accent, I can start the movie whenever I want, I can cuddle with a girlfriend (can't do that in a theater because the seats physically prevent it) or a cat, I can adjust the volume to my liking (theaters are usually too loud), I don't have to drive a long way to see the movie and worry about getting a speeding ticket or in an accident with a drunk, I could go on and on.
The main thing people like Cameron seem to be pushing with theaters is the social aspect. I'm sorry, I don't buy it. Who actually talks to or meets new people at a theater? Any socialization is between people who are already friends; if I have some friends that want to watch a movie, we can all meet up at someone's house instead (and then they can even spend the night...). I have no desire to socialize with random strangers in a theater, and in fact, this just isn't normal anyway. "Sharing the experience" is worthless to me. I'd rather share the experience with some friends at home. And I suspect I'm not unusual in this regard.
The only reason theaters did so well in the past is because people couldn't afford equipment that was even remotely as good as what a theater used. Thanks to gigantic LCD TVs at dirt-cheap prices, this has all changed.
