While there's a plot hole about Will Byers (Noah Schnapp) from season 1, he's still one of the best characters on Netflix's Stranger Things. He gets caught in the Upside Down and lives to tell the horrifying tale and is an important part of his friend group. He and Eleven (Millie Bobby Brown) have a special bond which gets even stronger in Stranger Things season 4 and allows them both to grow up more and find more confidence.
