Inside Llewyn Davis starts where it ends, in desperation and isolation. Moments recur, varied but not; characters change and don’t. Llewyn Davis sees himself in his incontinent father, his wide-eyed nephew, his various hosts and the cat. Ulysses is an interesting creature, always escaping, down the fire escape, on the road, on a movie poster, there and not there, almost like Schrodinger says, but more like an animal of eternal recurrence, life in a loop. The Coen brothers’ latest film is remarkable simply because it pretends to be simple, reiterating the basic truth that everything has already been done.
