At home. Movie theatres are expensive, and there's always someone disrupting it somehow. It's usually someone talking over the movie, or someone deciding that it's a good idea to bring their toddlers to an R-rated midnight showing of a movie. The cinematic experience is fun, but I don't really find it worth the money and annoyance. Plus, when I watch them at home, I can pause as needed and not have to worry about missing anything, I don't have to watch it at a certain time, and I can freely do something else while doing it.
