Classical Roots of "Winter's Bone"?

Am I the only person who saw "Winter's Bone" as a riff on Antigone?

It has a different beginning, true--her heroine's quest is launched by the appearance of Hermes Diaktoros in the form of the local sheriff. It has a different ending, true--we have Apollo Apotropaeos in the form of A-1 Bail Bonds arriving at the end as the deus ex machina. And it has a journey to the underworld called for by her duty to the family at the heart of her heroine's quest, but so (in a sense) does Antigone.
