It’s certainly worthwhile watching, primarily because of Marion Cotillard’s strong performance. The initial idea behind the story is interesting and includes some emotionally resonant moments; there's one involving Timur (Timur Magomedgadzhiev) that unexpectedly affected me—it wasn’t even the most intense part of the movie, but it elicited a powerful response. However, the cinematography and other technical aspects aren’t particularly impressive, and the script is especially disappointing. I may have been more aware of this because I was reading subtitles, but there are several instances where Sandra (Cotillard) repeats interactions with different people—it becomes rather repetitive. Cotillard's performance, though, stands out significantly. She conveys a great deal of emotion and authenticity, excelling in every scene and deserving considerable praise. Beyond her character, the supporting cast isn’t particularly memorable; they are adequate but I would have preferred a more substantial ensemble. I probably would have given it a lower rating if not for the lead actress, who is without question the strongest aspect of *'Two Days, One Night'*.
