In this Tom Sawyer-ish magical-realist melodrama, two teenage boys discover a fugitive (Matthew McConaughey) hiding out on a tiny river island in Arkansas. Turns out this fugitive (nicknamed "Mud") is on the run from bounty hunters. But he's just an innocent (mostly) fellow trying to reunite with his ladylove (Reese Witherspoon), who's stuck living at a rundown local motel. A lovely, if overly allegorical anti-fable from Jeff Nichols (writer-director of 2011's equally metaphor-heavy Take Shelter). 130 minutes PG-13.
