When Netflix unleashed The Haunting of Hill House upon its subscribers in 2018, not only were audiences engaged by the complex drama and unsettling horrors of the story, but the series also earned a number of repeat viewings thanks to director Mike Flanagan hiding a number of spirits within various frames in hopes of conveying the idea of a home truly full of ghosts. In the follow-up series The Haunting of Bly Manor, these hidden ghosts were once again incorporated, but rather than being unidentified spirits, each specter had significance to the events that unfolded in the home throughout its history.
