Review: In ‘A Complete Unknown,’ a cryptic Bob Dylan comes into view, gifted and callous

In the initial, refined section of “A Complete Unknown,” one often encounters the soothing tones of folk music – it’s a melody that seems to emanate from the next room, down the corridor, in a different venue further along the path, past the energetic tambourine player. You strain to catch the sound, as do the characters who seem drawn together, almost as if summoned by an unspoken invitation. Are they bonding to form a community? That might be overly romanticized. Instead, this is a snapshot of connection.
