Most critics respond favourably to Case 137, praising its sober examination of police misconduct and the investigative work needed to establish responsibility. Léa Drucker’s performance draws the clearest agreement: the reviews repeatedly credit her with giving the investigator authority, complexity and vulnerability. Praise also clusters around the procedural detail, from tracing officers through CCTV footage to making routine enquiries tense through editing, dialogue and varied footage. Several critics find that the restrained approach strengthens the film’s account of institutional obstruction.
Reservations concern pace and how far the political critique goes. Some find the investigation gripping throughout; others describe stretches as slow or thin. The Guardian considers the film less challenging than it could be, while Little White Lies finds the later moral debate conventional. The Wrap offers the coolest assessment, judging it competent but inessential. The spread runs from strong endorsement to mixed appreciation, with no wholly negative verdicts.
