The film deals with themes of mortality and a difficult father-son dynamic, but its gentle rhythm, touches of humor, and straightforwardness surprisingly create an uplifting viewing experience. Ed Harris delivers an exceptional performance that alone makes seeing this movie worthwhile. The script also plays a vital role in keeping the narrative engaging despite its basic storyline. The film’s central idea is based on reality – in 2010, the final lab offering Kodachrome processing, run by a family in Parsons, Kansas, briefly turned into a destination for photographers using that type of film. Appreciation of photography isn't necessary to find enjoyment here; it functions as a road movie and beyond its initial concept, focuses primarily on music. For those with an interest in the medium, the photographs featured were taken by Steve McCurry, and Ed Harris’s character is shown using a Leica M4-P camera.
