Red State is a horror movie. It is not filled to the brim with dick & fart jokes and pot humor. Red State is reported to not look like a Kevin Smith film--a sentiment that Smith himself touts with pride. Red State is also not a political movie. When the title was announced some vituperation from the political right came to bear, but previews and discussion of the film have revealed that it is certainly a horror film more than anything else, even when the internet seems to say otherwise.
Another twist on Red State is the way the film is being marketed. Typically, a $10 million dollar film will cost another $5-10 million in its budget for marketing. It's a typical Hollywood studio strategy. You make a movie, then advertise the hell out of it to try and grab a wide audience. Kevin Smith is taking a different route.
