The reviews lean towards qualified approval of Fat Girl, with praise clustering around Breillat’s frank treatment of sexual vulnerability and the sisters’ complicated bond. Critics value the close observation of seduction and emotional exploitation, even when they disagree about the film’s larger purpose. The young leads also draw praise: Anaïs Reboux for her dignified, inscrutable presence, and Roxane Mesquida for the boldness of her performance. Slant Magazine offers the strongest endorsement, finding insight in the deceptively simple storytelling.
The ending is the main dividing point in a broad spread of responses. Variety finds it arbitrary and disappointing without dismissing what precedes it; The AV Club considers it damaging enough to make an otherwise tense, subtle film repellent. Eye for Film also questions Elena’s characterisation and the film’s credibility. The consensus remains qualified, though three reviews lack accessible verdicts, limiting how fully their reservations can be described.
