Of currently running shows, I definitely like Stranger Things as well, The Handmaids Tale, but my faves are Star Trek Discovery, Outlander and Game of Thrones. I'm a sucker for scifi/fantasy.
I also watch The Walking Dead, but I'm thinking about stopping, cause it just depresses me when they keep killing characters I get attached to... <_<
Other series I've loved are Downton Abbey, The Pacific, Star Trek Next Generation, Avatar The Last Airbender, Friends, Sherlock, The Office.
