Gummo
There's some really transcendental imagery scattered throughout this.
I think people mainly find Gummo off-putting because it's radically non-judgmental of the characters and their surroundings, and displays a level of poverty that we aren't comfortable acknowledging exists so close to ourselves.
The type of movie that's equally misunderstood by both the people who love and hate it, and hits on something deep that even Korine probably didn't fully intend or realize as he was making it.
Also, what a tragedy that Linda Manz isn't in every movie ever.
