The Road (2008) for $6.61

In many ways a close adaptation of Cormac McCarthy's grim novel, The Road dutifully plods through the basics of McCarthy's nightmarish post-apocalyptic landscape: a father (Viggo Mortensen) and his young son (Kodi Smit-McPhee) try to survive as they trek along through the sodden, sunless remnants of some awful disaster.
