i think the last movie i saw twice in one weekend (or even multiple times) was blade 2. once on my own and once with my roommates.
beyond that...meh.
as for audience behavior, i tend to avoid most of the "big" movies because they don't interest me, or i see them on a week day after they've opened or the pre-noon showings when it tends to be other adults.
in Arlington, we have the Cinema and Drafthouse which does second run films and other events with food and alcohol, but also with smoking, so i don't really get to go there much.
