Maybe a popular work needs a common thread, in order to make the storyline more relatable somehow for the reader (or viewer); even if/when it's unintentional. Ultimately, the reader/viewer can draw parallels to their own experience and viewpoints, or they might just get emersed into the fictional storyline altogether. In the end, casting aspersions about anything, especially a work of fiction, with undeserved authority or apparent certainty as if it's a proclamation of facts or some natural law is misguided and too common these days.

Gonna leave that run-on...
