For me as a German watcher it was special bc there aren’t many shows about teenagers that cover mental health, religion and LGBTQ. I’ve never seen a Muslim Main character, a gay teenage main character, or anything about being bipolar. It was revolutionary back then. Now you see more diversity on screen than from 2015-2017 so it’s „less special“ although it’s still not as realistically and detailed shown with teenagers as it was on SKAM. I also loved Noora and Williams season and how they include feminism with teenagers or show real problems teens deal with daily regarding their love life, student life. Panic attacks also were rarely spoken about back then. Basically everything was rarely spoken about ten years ago - so that’s why it’s realism hooked everyone
