The Stranger Things series finale had an 18-month time jump - but was there a post-credits scene as well? Netflix's hit series concluded on Wednesday, December 31, with Vecna (Jamie Campbell Bower) finally being defeated and the Upside Down getting destroyed. There were a few casualties however with Kali (Linnea Berthelsen) and Eleven (Millie Bobby Brown) dying on screen ... although the latter is up to debate depending on who you ask. The battle wasn't the final scene of the show.
