“The Thicket” is a violent western created by celebrated author Joe R. Lansdale, the writer behind “Hap and Leonard” and “Bubba Ho-Tep.” It’s a rough study of survival from the author, with adaptation duties handled by screenwriter Chris Kelley and director Elliot Lester (“Aftermath,” “Blitz”), who are challenged to make something semi-approachable with a story that’s primarily about agony in many forms. It’s certainly not a friendly picture, but the rough edges of the source material are largely preserved in the feature, which tries to maintain a psychological portrait of bruised people while still participating in western traditions. “The Thicket” isn’t always successful with its storytelling, but it does create an immersive understanding of the era and its gun-toting participants, while a few casting treats certainly help the cause.
