No sooner has the viewer come to accept the Barrows’ thefts as bloodless, Robin Hood–style high jinks than the senseless, bloody death of a bystander recalibrates our moral compass; by the time the movie reaches its indelible finale, our judgment is once again rerouted by the excessiveness of the pair’s execution by an FBI death squad […]. If it’s possible for a film’s ending to feel at once ambiguous and definitive, Bonnie and Clyde leaves the viewer feeling torn apart without necessarily knowing why.
