I'm glad they say that, because it would be the last thing we'd need, but "totally original and un-derivative in terms if its world" are not the words I'd use when they have 40 spin-off of Game of Thrones in the making.
They, more than any other channel or streaming service, decided to continue numerous shows that started as limited series only because they had success. True Detective, Big Little Lies, The White Lotus and Mare of Easttown immediately come to mind. Their biggest hit this year was a video game adaptation and one of their few other current shows is Perry Mason, which is a reboot.
So while I at least appreciate they're not going to do a Sopranos reboot or something I still think the wording she chose is not the most accurate.
