Dude, I will say I disagree with you, but Im very very glad to find someone like you. In my opinion, all elements of a work of fiction must be treated equally. Writing can be just as powerful as art or cause the same amount of damage, if bad, imo. I also watched that video but what opened my mind about the subject was this post. Before reading that, I also thought that story and characters> everything else. But then, I started searching and studying more and I finally realize art, soundtrack, animation, voice acting, etc. can all bring emotions and be intelectually stimulating just like story and characters.
It makes me sick seeing people saying stuff like: "I dont care about art" because that is not an opinion, that is a lie. People 'think' they dont care about art because they never studied how it is used and thus do not realize its impact. Those people tend to think good art is just being pretty and therefore it is easier to make than a good story. Now even if I disagree that writing is inferior to art or soundtrack, it makes me really glad to see people like you, at least to balance the amount of overrate writing gets from the community.
