"Sir you can't bring in a video recorder into this theater"..Just imagine the pure confusion of the parents when they take their kids to the cinema to watch the new MLP movie. Parents that has no idea at all about the whole fandom.
That cinema has to be the weirdest one. You got the young kids that are there with their parents, you got those that masturbate to horses and you got the rest of the fandom; all collected in one cinema.
I would literally pay just to observe what the hell the outcome of THAT would be.
"Oh don't worry, I'm not recording the movie, just the moviegoers"
The ticket dudes would probably understand your reasons ahead of time as well.
