I have never watched John Hannah cry in a film and not shed sympathetic tears. This film is no exception. 

On the same day that Helen (Gwyneth Paltrow) is fired from her job, she misses the tube by a split second. Her life splits into what could have happened had she caught the train, and what happened because she didn’t.

This is not a comedy. There are funny moments, but ultimately it’s a moving exploration of one woman’s life, and how she is affected by those around her. It’s a philosophical debate marketed as a romance, and it does both.
