An intriguing if sometimes clunky film made fascinating by the performances of Kristen Stewart and Juliette Binoche. Both are excellent. The theme is decline and resilience and acceptance of ageing. Unfortunately, the movie adds a 3rd Act which is unnecessarily long and introduces new characters who should be no more than functional, but up that point the conflict and curious friendship between the women is central and engaging. Olivier Assayas demonstrates his command of yet another genre.
