LONGMIRE — One of the better summer series, Longmire, premieres Sunday, June 3 at 10 p.m. ET on A&E. It's a contemporary western crime thriller based on Craig Johnson's best-selling mystery novels, starring Robert Taylor (The Matrix) as the haunted-but-steadfast Sheriff Walt Longmire. He's a dry-witted, straight-talking widower still grieving the loss of his wife, yet getting the job done in sprawling, present-day Wyoming. —EG
