I think people here who are intrigued by In a Violent Nature but confused about its approach might be interested in reading up on the
Slow Cinema movement. Basically a genre of experimental film that focuses on long takes and minimalism and often features long stretches of people doing nothing but walking. Think the part of Twin Peaks season 3 where you just watch a dude sweep the floor for 2 minutes. Some directors in the genre have talked about the approach being to deliberately "bore" the audience.
That might sound counterintuitive (why would you want to make a movie that's deliberately boring?) But the best practitioners have made some truly hypnotic and transcendent work. It's not really about "boring" the audience, more about reflecting life as it is. Life, oftentimes, is boring, repetitive, alienating, sad without being overly tragic, lonely without being bitter. Slow cinema is a movement that attempts to reflect that.
That sounds like what this movie is going for, trying to make a movie about drawing someone into someone's empty, simple life. It's just that this time, that someone is Jason Voorhees.
