Season 8 was shit because D&D gave up on the show to go on and do other shit. HBO even wanted to give them more time and money but they declined. I don't understand how people can still defend Season 8. Seriously? So many plotholes, characters becoming useless like Jon yelling at a dragon, Tyrion being useless, same with Varys and of course "BrAN tHe BrOkEn". It could have been done better in many ways, but they rushed it because they wanted to get it over with.
I don't think I have any interest in those prequels unless it comes with thundering reviews. I'm done with this universe for the complete shit show season 8 was.
