Home, for all the reasons you stated, but also because I get motion sickness in theaters. As a kid, I often had to go to the bathroom and throw up when I saw a movie at the theater, and I thought maybe it was the candy or fountain soda causing it. By the time I realized it was actually motion sickness, I had also developed an unconscious association between getting sick and the smell of theater popcorn. So now I sometimes get sick at the movies just from the smell. I try not to go unless there is a really good reason; I haven't been in two years. :(
