Travis Lytle’s review published on Letterboxd:
A portrait of an artist as a soulful wanderer through life, "John Mellencamp: Plain Spoken" allows the artist to present his portrait with self-effacing clarity. As a Mellencamp performance unfolds at the Chicago Theatre, the singer-songwriter narrates, in plain spoken mid-American poetry, an autobiography that takes the film's audience from his youth to the present day. The songs performed coincide with the thematic points of Mellencamps's straightforward narration, providing an ideal soundscape for Mellencamp's weary voice. "John Mellencamp: Plain Spoken," eschewing the typical talking heads and vintage film clips of the standard music-based documentaries, is a refreshing, slow-rolling, and completely compelling story of a musician told in his own voice.
