For someone who asked about the Coco Chanel and Igor Stravinsky movie, those bad reviews are made by people who don't understand fashion nor art. They obviously come from people who are only interested in mega hit movies with famous cast.
The movie is very beautiful, especially the story about the love affair between Coco and Igor. The movie literally shows the empty love life of both characters - and how special they feel after secretly getting together.
It's an amazing movie, really. Definitely worth watching for people who understand what real treasure is.
