Honestly, I didn't like season 3 because all it was was focusing on Bryces death and no one liked Bryce so it sucked. But I liked season 4 a lot because it focused on Clays mental health and that's really important especially these days.
Not really because the topics in the show needed to be discussed in a real way and i think they were successful at doing that and making it really interesting at the same time. it’s one of my comfort shows i think it’s so good. however if you get really triggered by those types of topics i think you should watch it safely with an adult or someone who can comfort you. or not watch it at all. it does give many warnings and tw so just keep those things in mind.
