Hard going
This is tough one to watch as the main character does not behave like a mature adult. Time and again, she makes crazy decisions. Her teenage daughter seems to act more like a grown up than she does. At no point does she appear to acknowledge that he daughter is in a state of grief having just lost her father.
The normally excellent Keely Hawes has been saddled with a poor script to play a frustrating and unsympathetic character.
