Oh yes, The OA.. That ending as well. I was like oh man, next season is going to be something. Oh.. never mind. Then there's Santa Clarita Diet, Dirk Gently, those cancellations left such a bad taste in my mouth. Recently The Midnight Club and Warrior Nun was also cancelled - can't say I was in love with the WN but I got invested enough that I needed to see how it ended. At this point it's not worth starting something on Netflix.
The relief I felt when I saw that From had already been renewed for season 3, I think it was before season 2 started airing or just as it started, omg. And Silo has been renewed for season 2, thank god.
