Not Enough Time
While I was not disappointed with the last season of Game of Thrones, there was something just a bit off. I said to my friends that I think they needed more episodes to make the twists and the turns feel more real and not rushed.
YouTuber Just Write had that same thought, but explained it way better than I could in a great deep dive into the narrative of Season 8 and the problems the writers/producers created for themselves.
