The gritty, desperate Ozarks milieu of “Winter’s Bone’’ feels so real, so right, that you only slowly realize you’re watching a detective movie. It’s those noir bones that give this social-realist drama its punch, as if Humphrey Bogart had been recast as a 17-year-old girl and dropped into the poorest corner of America.
The setting may seem familiar if you saw last year’s estimable art-house hit “Frozen River.’’ Same numbing poverty, same hard women and no-account men holding on by their fingernails in shacks and trailers on rutted back roads. The people in “Winter’s Bone’’ are meaner, though, and more proudly, even criminally, reclusive. They’re umpteenth-generation mountain folk, but the moonshine stills have given way to meth labs, and the revenuers are now sheriffs in sleek county police cars.
