Like all of Mike Flanagan's projects with Netflix, The Fall of the House of Usher left viewers completely satisfied. The series follows the last days of the Ushers, a billionaire clan, as death takes them one by one. The Fall of the House of Usher is based on Edgar Allan Poe's homonym story, and each character takes their name from a character in Poe's bibliography.
