This is not for you if you're looking for something light and uplifting as it's a short sharp reminder that life and relationships aren't perfect and many people suffer from mental health conditions like depression and anger issues, sometimes functioning "normally" on a day to day but sometimes it can all be masked, and people simply get by.
The acting is fantastic by all the cast. Some lighter moments in the lead character's extreme outbursts but I felt they could have shown a nicer side of her too, as we are all a mixed bag and feelings and emotions rarely remain the same (whether happiness, anger, sadness, or grief). It would have been good to see a little more about the father and son, their lives outside the home, but all in all a moving take on sisters who are complete opposites in many ways...
