Fandoms
According to Urban Dictionary, No Country has gotten a bad rep over the years because of its snotty fan base that can't handle the possibility that someone might not like this heartbreaking work of staggering genius. So, yeah, you could say there's a fandom.
That's not to say everyone loves the movie. Plenty of viewers find themselves frustrated by the way the movie upsets their expectations, like by killing off the main character without any real explanation of how it happened. To many viewers, this amounts to bad filmmaking. To fans of the movie, that's just the genius of Joel and Ethan Coen messing with their viewers.
Like most fandoms, though, they're probably not listening to you.
