Will Byers was supposed to be the central character. The show started with him, it should have ended with him. Instead, he spent the entire final season being a background extra for Eleven's messianic complex. His connection to Vecna was barely utilized until the final battle, and even then, it felt like a plot device rather than character growth. He didn't get a hero moment; he just got trauma. After ten years of waiting, Will deserved to be the saviour of Hawkins, not just the victim.
