My wife has the same get out of the house attitude. I just don't think it's getting out of the house in any meaningful way that's different than staying at home. Either way you are sitting in the dark to watch a flick.
However, in one situation you can control the environment and in the other you are at the mercy of the theater and crowd. Movie theater experiences to me are wasting time driving through bad traffic, waiting in line to buy a ticket, waiting for the ticket check to accept you in, waiting through the endless commercials and previews, dealing with annoying people in the theater, spending $7 on a bucket of popcorn that tastes like stale ball sweat, then driving back home through bad traffic.
I'd rather stay home and save the $50 for some excellent steaks or a ton of pizza and ice cream, or, buy some 7-11 nachos and some Orville Redenbacher's and pretend I was at the theater. And is there really that much to clean up after yourself at a home movie event?
