The show is based upon the novels of Craig Johnson and brings the Western to modern-day life. The Wall Street Journal said of the show:
"Longmire" is the best of two worlds: a modern crime drama with dry wit and sometimes heart-wrenching emotion that's also got a glorious setting under the big sky of Wyoming. Based on the novels by Craig Johnson, the series revolves around Sheriff Walt Longmire (Robert Taylor) and a small clutch of deputies in a sprawling northern county adjacent to a Cheyenne reservation. If it weren't for a few modern conveniences, like cellphones and trucks, it might as well be 1875, so rugged and unspoiled does the scenery look.For gunnies, this show is wonderful. Part of the first episode centered around finding a 45-70 Sharps rifle that had been used to kill the victim. Longmire himself carries a 1911 and has a Model 94 30-30 as a truck gun.
If Justified is Miami Vice come to eastern Kentucky, then Longmire is Gunsmoke come to 2012 Wyoming. The show airs on Sunday nights at 10pm on A&E.
