I was hanging out with a friend and their roommates started playing this in the living room. I ended up watching it out of morbid curiosity, but more so because we were stuck in the same room.
This movie reminds me of the kind of kid in highschool who would write violent fanfic about someone they don't like but can't touch- but acted out in a film for over an hour and a half. It's sadistic and graphic schlock. Most of the movie is just a man begging for mercy from the main character torturing him- and there's hardly any tension in this power dynamic, it just plays out like a power fantasy. I ended up feeling more empathy for the villain by the end because it's kind of hard to to root for a sadistic teenager dropping terrible one liners.
At a glance the film might've been trying to make some fake deep social commentary along the lines of "OOOuGH what if the victim became the villain in the end??". If it was, then it fell flat because the film never really challenges the main character's actions, and I just find that very uncomfortable in the cringe way.
