Now, honestly, I get where they're coming from, even if I disagree with their methods. My question is, why announce it? Not every cineplex features every film out there. So, maybe this particular chain just doesn't carry it and doesn't make such a stink about it. Why do you have to alert the world of your supposed moral superiority? These decisions never go over well (like when Utah Jazz owner Larry Miller decided Brokeback Mountain was too gay to be shown in his theaters) and only serve to draw more negative attention to Utah and it's perceived uptight attitudes.
Yes, the film isn't for everyone and it may not even be artistically or culturally relevant. But, it isn't an actual porno and is only R rated. Just let some other chain show it and shut up about it.
