I don't typically like comedy shows that much, but Brooklyn Nine-Nine is so amazing. I finished it 15 minutes ago and had to put a post here. I've been watching this show since I was young, it's always brought me laughs and made me happy.
You should definitely watch it, the characters are so fleshed out, there's a lot of representation that I don't see in other shows, and it's also very comforting.
So, I recommend that you watch this show, you won't regret it!
