Pokemon's been one of my favorite shows. It's light-hearted and fun so I have fond memories with it when I was younger. Same goes for Hey Arnold! I'm very fond of Jane The Virgin and Hello, My Twenties! (Age of Youth is the original title in Korean; watch it, it's really good!) Friends is pretty fun as well.

and probably a ton of others I've forgotten that people may or may not have mentioned already.
1. Bates Motel (even though it has ended, it will always be my favourite).
2. American Horror Story seasons 1-3 (not a fan of seasons 4-6. To be fair though, I haven't seen all of season 6).
3. Stranger Things.
my favourite tv shows atm are brooklyn 99, and rick and morty.
i don't need to say anything for rick and morty because i'm pretty sure everyone knows the show, and it has a huge fanbase and i mean the show practically speaks for itself it's awesome as heck
brooklyn 99 however, is severely underrated in my eyes. it's got everything a cop show needs funny jokes, serious moments but most of the time unserious, and terry crews from white chicks in it what more could you want???? i like that they don't make the whole show just about being a cop tbh. there was even an episode that only revolved around who stole somebody's ice cream who doesn't want that comedy gold in their life the characters are all so endearing in their own way and it makes me so sad because i've recommended it to so many people, and they either say they'll watch it and don't, or they'll watch it and stop watching after like 1 episode.
