The Mule is a respectable entertainment from Clint Eastwood. The familiar territory of a vacant father having a late in life crisis and reconnecting with his ex-wife, daughter and granddaughter, lacks a true emotional resonance. Becoming a drug running mule becomes the catalyst for his alteration. It’s the type of connect the dot plot that leaves audiences cold. This is no Breaking Bad drug film. The drug dealer and mule running scenes are flat. But still we can appreciate the pain staking film making that Eastwood excels at. The slow burn gives the characters depth so we should be thankful. Yet we expect a master work from the man who gave us The Unforgiven, Mystic River, and Million Dollar Baby.
