< the latter is the equivalent of having people talk behind you in a movie theater.

And here we have the center argument why some people don't go to a movie theaters. Its noisy. The volume is not set to a personal setting. Its crowded (and by definition, again noisy). While one can ask extra loud people to tone it down, you can't eliminate all sound a crowd has. So long people talk to just the person next to them, that is often considered acceptable. The only other option is to view the movie at home.
