I think, I've already watched everything on Netflix, Hulu, HBO max, Amazon Prime and Disney+. What's next? What can you suggest? What other subscriptions do you have?
I also like watching TV series too much. However, I still have much planned to watch. Try installing CineHub (https://www.firesticktricks.com/cinehub-apk.html). It's a streaming platform that doesn't have geo-restrictions that filter out a ton of content depending on the country you connect from.
