Back in familiar Western territory, Bridges plays iconic figure Wild Bill Hickok (Keith Carradine played the same character in Deadwood). David Arquette is Jack McCall, a young man who holds a grudge against Bill, and plans to seek his revenge.
It's a solid enough study, but it it fails to reach the highs of the similarly-themed Unforgiven, The Assassination of Jesse James, or even TV show Deadwood.
Laidback Dude? He's clearly carrying a lifetime of guilt on his mind.
