Season 1, amazing a straight up 10! Hard to watch but very very well done with an amazing lead and themes people needed educating on! Season 2, not really necessary because Hannah's story has been told and it's taking away her shine. But ... it was still good in dealing with other aspects of high school life that occur more often than we realise. Season 3, just no, this is irriversal damage by casting! This British accented know it all will DO YOUR HEAD IN THROUGHOUT THE HOLE DAMN SEASON! Ruined. Worst cast choice. It would be so much better without her in it at all.
