For me, going to the cinemas is enjoyable, there are no distractions, and it's satisfying recognizing something I've worked hard to learn (other benefits are here). It's finally possible to go to the movies again here in Beijing (yay!).
However, I feel like I would benefit more if I prepared prior to going to the movies, but I'm not precisely sure how to prepare. It seems like I should try to "book up" on terminology I anticipate will be in the movie.
Question: What "homework" can I do to benefit more from watching a Chinese movie?
