“Diablo” (*1/2 out of four) was a draggy Redbox western that moseys along too slowly through familiar terrain as a young Civil War veteran (Scott Eastwood) goes on a journey through the wilderness to save his kidnapped wife and along the way is encumbered by a bad guy (Walton Scoggins) who is determined to stop him. Beautifully photographed but offers little action and little else you haven’t seen done before- and done better- in “Lonesome Dove”, “Unforgiven”, or the more recent “The Revenant.” Aburrido!
