premise: But Sam Peckinpah's The Wild Bunch (1969) features existentially disillusioned outlaws going out in a montage of bloody chaos, Butch Cassidy and the Sundance Kid (1969) is an outlaw buddy film, and Dances With Wolves (1990) attempts to revise entirely the concepts of both order and the west.
hypothesis: Dances With Wolves was a much more popular film than The Wild Bunch.
