This movie is a "remake" of a very famous Italian modern theatre play, author of which being Emma Dante, a Sicilian playwright and director.
Very interesting point was the production design of the apartment of the sisters - very extravagant, seen as the 6th sister.
The film is heavy, very very indie. For me it was practically a movie
on the processing of mourning and enormous sense of guilt that has not been processed. The sisters kinda literally fall apart because of not getting over the tragic accident in their youth.
I was not convinced by the cast of adult sisters, because together with costume and make up choices it seemed something surreal - three sisters live together for decades in a real decay, not only external, but also internal.
The story of the "guilty" sister was also unclear. Her reading, her life, her story - without a clear meaning.
