Jane Lapotaire give a tour de force performance as an angry lesbian who disrupts everyone around her in her life. But it's not as simple as that with difficult topics such as mixed sexuality, and child abuse issues. Even today, 2022, this material would be considered courageous.
It is billed as a love triangle but that is a gross oversimplification of the complex relationships between all of the characters. The three main characters are a man and two women with a brief appearance of two other women. All five lives are tangled by this strong, feisty, troubled lesbian main character. Add to all of that there are religious and political issues discussed which are just as relevant today as they were in 1975/1976 when it was made and shown. There is also the British class system interfering in their lives. Television drama is rarely as good as this. Acting by everyone, including two children, is superb.
