The movie starts out a bit slow. Basically we're introduced to the protagonists and find out why they are holed up in the middle of nowhere. Then the action begins when one of them sees a KKK execution in progress and intervenes. From there, you get pretty much non-stop action as the two factions battle it out.
What makes this a "horror" film instead of an "action" film is the copious amount of gore. The KKK, who are more akin to cannibal families a la Texas Chainsaw Massacre, than your usual KKK members in films are partly responsible for that gore and some of the sadism, but so are the protagonists as they quite sensibly avoid holding back while fighting a bunch of psychos who outnumber and outarm them.
And that's why I found it a guily pleasure. It doesn't have an amazing plot, or a profound message, or impressive fight scenes, or anything. But it is refreshing to watch a horror film and not have to keep thinking "WHY DIDN'T YOU MAKE SURE HE'S DEAD!!!". And, heck, it'll always fun to see any group of Klansmen get what's coming to them, and that's a major factor in making this a guilty pleasure. No woke preaching about intersectionality. No stunt casting (yes, the KKK are miraculously all white males in this one). Just good guys fighting evil racists.
It is well filmed -- no cheap digicam footage feel or anything like that. The fx are effective enough. Heck, I even like the titles which were pure Tarrantino. And I always liked a 70s rural setting for horror. And bonus points for not one single annoying teen in the film.
