A woman it protest against the local police department hires three billboards to annoy the police into doing something. It's a Drama I suppose. The comedy tag doesn't make sense, well if you want laugh at dumb hicks or when someone says the N word or something else offensive, this movies your own comedy. I don't like this movie. It starts with the parodied version of the US states the cities don't like, where most are dumb and racist. I think you have to accept that premise to begin with, to enjoy this movie. It leads on through with the main characters failing to change and continuing to be selfish. Of course trying to flip the usual narrative of storytelling, to try and accept depression and the doomed reality of society? That's it maybe this is a dark comedy, a dark comedy for the anti-government types, this was made under Trump after all.
