There are lesser-known streaming services such as Hulu and Apple TV+ with great content too. There is also Shudder for the horror fans. From Hulu, I really recommend you to check out a philosophical scifi series called Devs. From Apple TV+ I liked the series See, Servant, and Calls. They are also producing the series I am expecting the most this year called Foundation. From Shudder there is a cool horror film from Argentina called Aterrados (Terrified).
Netflix, Prime video, Disney and HBO are the main services, but the other ones also have some hidden gems.
Thank you very much for the recommendation, actually the only series I've seen on Apple TV was See, and I liked it, although I hope they bring out a second season and improve some things. I'm going to take some time to analyze these two platforms. Thank you very much for your great comment.
