Did Stranger Things 4's Ending Kill The Best Upside Down Theory?!

A popular theory since the first season of Stranger Things may have been debunked by season 4's ending reveal that Henry Creel is Vecna.Stranger Things has always been heavily tied to Dungeons & Dragons, but season 4 might have crushed the best theory surrounding D&D and the show. Stranger Things begins by introducing a young group of D&D players, including Will Byers (Noah Schnapp), who then goes missing. Over the first season, the young friends uncover a parallel world, the Upside Down, and a dangerous monster, the Demogorgon. The names come from the lore of D&D, as the characters discover that their situation eerily mirrors the game. The trend continues, as they name the next major antagonist the Mind Flayer.
