It feels like the main character is an exaggerated form of how some people perceive themselves: constantly doing something so horrifically taboo that no one wants to mention it. The giant scar on his face is a great symbol for this: it's so obvious, but no one is willing to talk about it. And when they do, he makes up some excuse and refuses to actually address the issue or seek help.
So I forced myself to sit through 36 minutes of this before turning it off. I started thinking of turning it off about 15-20 minutes in. I was sick of Derek's face, sick of his attitude and sick of his inarticulateness. I don't need to like a character but I do need to at least find them interesting in some fashion. Nothing here but surface rendered in relentless searching close ups - with nothing to find.
There's something unique about Radwanski's approach that really does deserve more than 2(.5) stars. A film as unpleasantly awkward as its protagonist, but never exploitative, exploring the character with an unmerited depth of grace... eliciting empathy, almost against the viewer's will, via uncomfortable, visceral close-ups and other impositions of intimacy. Like a nice & well-intended but unwanted, onerous gift.
