If you think Season 8 was bad just remember the OG outline for Game of Thrones George had

Sansa would choose Joffrey over her parents and siblings and give him a son

Jaime would kill everyone in his family who was before him in line of succession for the Throne and Blame it on Tyrion who would join with the Starks

Jon, Arya and Tyrion would have a love triangle

Jon and Arya would end up together at the end
