I get it. I really do. The writers of this new TV series obviously have some issues with their own life choices and now that they are either middle and/or old age they are second guessing the life/career choices that they have made. This is by no means a new concept as anyone who is now past the age of thirty (30) something has most likely looked deep into their current situation and wondered how different their lives would be today if only they had made one key alternate decision and/or life/career choice.
This series simply explores the possibilities of what one man's life would be or could be depending upon the life partner (s)he chooses as well as their career choices.
I am a happily (twice) married retired senior citizen with three (3) adult sons and two (2) grandsons so far and wishing for more grandchildren. The series title is most appropriate as this ordinary Joe (James Wolk) provides his audience how one's man life is lived as a rock star, a hospital nurse, and also as a police officer as his own dad was until his father lost his life saving others during the 9/11 attacks in New York City.
The series has a similar feel as the multiple Emmy Award winning (2016 - 2021) series "This Is Us" as both series explores both the past and present periods of a persons life story. I believe if this series sticks to maintaining a more dramatic presence rather than a sci-fi genre it will sustain a large enough audience to win a few Emmy's of its own.
I give the series a positive 8 out of 10 IMDB rating.
