The later known as the first season of The Sinner, I can only say that it is impressively good, what an excellent story of a crime and other issues such as addiction and loss of control, that's exactly what I relate of the two protagonists.
Personally I have not seen the other seasons, but my mother has and it is one of her favorites.
It is so, hence the connection between the two, this series is intriguing, I hope the other seasons are the same, thanks for reading and commenting, greetings.
