I do that, discovered lots of good movie that way, and discussed different perspectives etc... Why would you need a cinema or watch a movie together?

Do you only discuss books you have read with and at the same time as your friends?

You sound like an antihermitite. Are you an antihermitite? Do you have some kind of a problem with me watching a movie at home in my mountaintop retreat, next to my bearfriend, who is watching a completely different movie on another screen? Does it disgust you that we enjoy each other's company without ever having a single conversation?

If I wanted to go to dinner and talk, I'd hang out at roadkill point with the crows, and make fun of the redtailed hawk behind her back.~

I remember back when going to the movies at a cinema was a great way to date someone without letting them know exactly where you lived--in case they turned out to be both wrong for you and obsessive--and without revealing immediately that you can't hold up your end of an unprompted, free-form conversation for four whole hours. It's a lot better value when you don't have to pay for your kids' tickets and meals, too.
