Series that gained popularity owing to their conspiracy theories

A boy goes missing in a small, quiet town, a strange girl with a shaved head turns up with no memory of where she came from, and the government lab sitting at the edge of town has clearly been up to something it should not have been. Reportedly, the show taps into a real program that actually ran mind control experiments on people, which gave fans enough reason to believe the whole thing could be based on something real. Between seasons, the theories about Eleven, the Upside Down, and the true identity of the final villain took over the internet completely. Created by the Duffer Brothers, featuring Millie Bobby Brown, David Harbour, and Winona Ryder.
