Why are you listening to them when you could just watch the show and make your own opinions? Maybe that's how the duffer bros intended it, but that's absolutely not how it came across the screen. I think they got a little high on their own supply because absolutely nothing whatsoever in the show or anything eleven did conveyed the idea that she was supposed to represent childhood magic. I think they had just read IT maybe or were confusing ST for for a random Stephen King story because there was nothing of that at all in the show. It wasn't that kind of show, any metaphors or analogies are surface level. So you can read their botched interpretation that clearly didn't come through in the final product or you can just watch the ending with media literacy and see that literally every character remaining gets the happiest possible outcome.
