New Genre 

The New genre supernatural was used because demons appeared, there were pop ups but ghosts possess just in case, the film was creepy and it was a great '80s movie since The Exorcist (film). What it appears to be that ghosts were especially haunting the hotel, Supernatural is all about ghosts, fantasy, science, spirits, demons, and haunting. That's it, because Supernatural needs to be the new genre in the film.
