Lawrence Roeck's second feature has the skeleton of an interesting symbolic western -- at times even a western psychological thriller -- but the screenplay never provides flesh or a beating heart. The attempt feels like a rough draft. Despite its short running time and dislike for extra details, it locks into a loose rhythm in the early going. Walton Goggins' character, played with a wicked spirit, brings a great deal of life to the film in his brief scenes. Goggins' presence begs for comparisons to The Hateful Eight, which wouldn't be in Diablo's favor. Eastwood, upstaged by Goggins and Glover, takes a bold move in his willingness to so directly invoke his father. The two look uncannily alike. His primary acting strengths lie elsewhere, but the flimsiness of his character here can be chalked up to poor writing. Technical credits are strong, and despite a somewhat foreboding score, the film looks excellent for its budget.
