The difficult relationship between mother, daughter and granddaughter, hidden secrets, unspoken truths. The development of the story and the discomfort as the story unfolds, the brilliant portrayal of the characters and a roller coaster of (my) emotions. If you are devoid of emotion, you might not feel the impact of this great film but for all other mortals, it will leave you astounded. I'm so glad I saw this film, tricky as the subject actually turns out to be. 5 stars from me.
