Wilson proves to be a mesmerizing if unlikely serial killer, his flat, Midwestern delivery ringing more sincere than sinister, more Charlie Brown than Charles Manson. His voiceovers purportedly allow us into the mind of a killer, but what we hear isn't all that different from what we see. Vann isn't faking the nice-guy veneer, he is a nice guy, with this one little quirk. Clearly, this is not your typical edge-of-your-seat thriller, but the slow, dreamy pace is nonetheless entrancing. There are moments of intense grace and humor here, too. Janeane Garofalo breaks away from the smart-aleck mold to portray a postal employee smitten with Vann, and Mercedes Ruehl takes a compelling turn as his troubled landlady. "I like the detail of a thing," Vann says. "Especially if it's got a purpose." While we may not know for certain whether this film has a purpose, the details dare you to stop watching, even for an instant. --Brangien Davis
