A British Mean Girls with no jokes. Played straight down the line, this is a tale of female loneliness. With echoes of the start of Carrie, this is a film about the outsider, what it’s like to be permanently locked out of the society the rest of us seem to share in with ease. It’s also about mother-daughter relationships, and how we can need them most at the times we have pull away from them to grow. The ending is horrendous and brought me to sudden, stinging tears.
