”O Coen Brothers, where art thou?” you may ask during the bumpy first half of the ”Blood Simple” masterminds’ broad as a barn-door retake on Homer’s ”Odyssey,” O Brother, Where Art Thou? Transmogrified into a picaresque tale of three Depression-era chain gang escapees (George Clooney, John Turturro, and Tim Blake Nelson), the script initially seems like a string of toothless Southern caricatures. But fine turns by ”Raising Arizona” alums Holly Hunter and John Goodman — and T-Bone Burnett’s old-timey soundtrack — eventually vivify the movie.
