5 stars "One of the best animations in recent years... matches Spike Jonze’s Her as one of cinema’s most devastating and profound studies of loneliness and the fragility of emotional connections... There’s such tenderness to the storytelling, such empathy and emotional depth, that it broadens the film’s potential audience from kids, who will respond to the cute characters and gentle wit, to adolescents and adults, who will recognise the angst and awkwardness of trying to function alone... one of the most persuasive love letters to the city of New York." - The Guardian
