Umbrella academy?? Nothing like chicago fire, but I also love chicago fire and stranger things and I really love it. It does get a bit violent tho.
Idk where you can watch it, but station 19 is fabulous (I think there are 5 seasons of it now???) which is also about firefighting. However it does sometimes feel a lot more about their personal lives than about the job which is different than chicago fire.
Is chicago fire up to season 9 on netflix in the uk?
