Manon Dumais of La Presse rated the film 7 out of 10, praising Scott's handling of the balance between comedic and dramatic tones.^[3]

For Cineuropa, Aurore Engelen was more mixed, writing that "unfortunately, the film chooses to age its actors (and to make them look younger) in a way that risks distracting from the story, especially when it comes to Leïla Bekhti and Jonathan Cohen who are playing a mother and son in the film, despite everyone knowing they're from the same generation. Casting "real" celebrities opposite "real" actors is also problematic, much like the film's tendency to explore tragic events (notably a succession of deaths) from Roland's viewpoint, confining us solely to his perspective to the detriment of the film's other characters, which might prove equally disconcerting for audiences."^[2]
