Tinfoil hat time:
I think we started off great with La Llorona, El Cucuy, Vampyre and WTMN. Keeping with that consistent quality, I'd verge to bet we'd be entirely all original by now with IPs being a rarity. Then Murdy ran it into the ground, drilled into the foundation, mined into prehistoric times, dived into the center of the earth, and dropped it in the 7th layer of hell with the god awful Black Sabbath, ACGTH, and Clowns mazes that the GP never wanted anything original ever again if it meant we had to have abominations like those. This isn't even mentioning Universal Monsters Remix -- he OWES us a genuine UCM maze after subjecting us to that diaper receptacle -- FOR TWO FU%KING YEARS!
But maybe that was the plan. Maybe he hated doing original mazes and so he just made them consistently worse until they tested on surveys as the lowest ranked. Now he'll always have the excuse that Hollywood is branded this way and corporate won't allow it. CHESS NOT CHECKERS.
I'm onto you, Murdy...
