They both walked back everything the previous movie did, I don’t know why you’re insisting that Abrams was involved in the writing for 8. Abrams’ position as executive producer on 8 doesn’t mean what you think it means, he only gets that credit because he did the movie before that as part of the franchise, it’s not always an active role.
JJ was the executive producer of 8 so I think we can probably blame both of them.
