At the end of last month, Netflix released a trailer for the nonexistent romcom in the spirit of “Stranger Things.” A romantic comedy was called Love in the Upside Down. In this romcom there would be no parallel worlds, alien beings and scientific experiments, and in the center of the narrative there would be high school students Nancy, Steve and the weird Jonathan.
