This series tells you more about the events of the teen series "13 reasons why" (see reviw on the series itselfs). It is purely an informational series and in my view it is also rather intended to prepare parents, guardians to be able to support their children while watching the teen series itself.
The explanation is far too difficult for teenagers themselves, but it does ensure that certain taboo topics can be discussed. In my view, it is a series that opens our eyes to the common problems in schools. It contributes to the mental well-being of our younger generations and shows that it is sometimes difficult as a teenager to raise the problems with adults.
