Portrait in example sentence
As I say, if "La Maman et La Putain" is intended to be nothing more nor other than a portrait of Alexandre, Veronika and Marie, three individuals whom any even halfway decent person would never admit into their company let alone their home, then I suppose there is a kind of legitimacy in praising the director for being "unflinching" (though why one should even feel like "flinching" once one had consciously opted to create such thoroughly repellent characters to filmically observe I can't imagine).
