Larry Clark is a horrible person.
That being said, he has made one film in his career that is at least worth your attention, not because it features teenagers engaging in promiscuous sex (which it does), or gratuitous amounts of male nudity (which it does), or incredibly awkward/uncomfortable dialogue and a plot that makes you squirm (which it does).
No; Bully is worth your time because it actually has something to say. KIDS, the film Clark is best known for, is a piece of shit because it has no message and no moral (the same goes for KEN PARK and WASSUP ROCKERS). It was just about kids giving each other AIDS. Luckily, no one gets AIDS in this movie, but some people die, some people do deplorable things, and it will make you feel like shit in the end, but one thing you won't be able to say when it's finished is that Larry Clark never did anything worthwhile.
