It feels like that writers sat down together and pitched ideas which controversial topics they didnt touch yet.
Mental disorders.
More gays.
Police survellaince.
School shooting.
Riot against the police.
HIV/AIDS.
Then took all ideas and put them together in the fourth season. Do they make sense together? Absolutely not. It lacks any coherence, characters act like they all lost their mind and almost nothing they do has any future consequences. The series was trying from the beginning to depict teenage issues as realistical, but this season was ridiculous.
It obviously doesnt matter, because the end was full of emotions and everybody will remember the end.
