In 2017, someone posted a file online and called it a “leak” of the season 8 of Game of Thrones. Some people were skeptical about this leak but many people loved what it said. Fans thought it was a perfect ending to the series. If it really was the original script, the writers would’ve been forced to make a new one. This is probably the only logical explanation for why the series ended in such an unsatisfying way for so many fans.
