The Stranger Things series finale left fans divided, and some viewers are even convinced the ending was fake - with a secret extra episode still waiting to be released. The hit Netflix series came to an end on December 31 after five seasons, which were released across the span of nearly a decade. The last episode wrapped up at 2 hours and 8 minutes, but some fans weren't thrilled by how the story concluded. In the days since the finale premiered, a viral "Conformity Gate" theory appeared online claiming there were Easter eggs pointing to another episode.
