EDB is not the only example of a movie bombing but there's still a maze for it. Dracula Untold, anyone remember that movie? The Thing: Assimilation? The 2010 remake of The Wolfman? All have been mazes at HHN, but none of the movies exactly lit the world on fire.
Heck, look at how Exorcist: Believer is still going at Horror Unleashed, and no one even remembers that movie anymore. Certainly, no one was asking for it to be immortalized in a year-round haunt, but here we are.
There could be other reasons for it not be used, but box office failure is not really one of them.
