The movie is a remake of a 2013 film and is directed by the same guy who made the original.
It's about a middle-aged woman living in LA (or it New York? Idrc) and dating.
The reason it's one of my fav movies of all time is that Julianne Moore gives a performance that is so human that you can see yourself and everyone else and all our normal human experiences in just one woman who is living her life and dating, it's a beautiful experience.
