A film composed of nothing but dialogue, restricted point of view story-telling and a literal ticking clock of building suspense, Circle toys with the deep-seated morality play of the human condition, though falls just short of properly exploring it. It would have benefited from fully embracing its ambiguity in place of a definite answer to the scenario, as the attempt to deliver a shocking twist ending instead only succeeds in robbing the audience of the chance to explore and discuss their varying interpretations.
