Films are made for many purposes and I don't know what this one is about. They say it is a psychological-thriller, but yes, there is some psychology in it, but definitely no thriller, just a boring drama which means a character study material. The entire film was shot in a lake house and occasionally its surrounding area. There is no story in it, just the characters and they're being themselves that narrated in the days basis for a week, but those days were from the random years without a clear picture of what date, month or the year.
Writer and director Alex Ross Perry's psychological drama has a raw and magisterial performance from Elisabeth Moss. She plays Catherine who with Katherine Waterston as Ginny are two women who grew up together and are spending a week at a remote lake house retreat which they did the previous year.
This year Catherine's mood is in turmoil possibly due to the death of her father and the ending of a relationship with her boyfriend. Both women realise that they have drifted apart even though they always seemed to have had a troubled relationship with a constant needling of each other.
