I think the history lesson Murdy gave made this feel different to people, along with the "multiverse" aspect. The details are important, sure, and give so much context. But when you're going through, it's literally going to just be a slaughterhouse like any ol' slaughterhouse. The music is going to have to keep this maze on its shoulders if it wants to be distinctive from any other slaughterhouse maze -- but other than the first film's sound effects and the remake's soundtrack, the rest of the series doesn't have anything else iconic enough to pull from to make it feel distinctive. Funny enough, TCM kinda set the standard with the slaughterhouse aspect at Haunts way before there was ever a proper TCM maze, but the haunt industry has driven it into the ground.
I would love to be wrong and this maze rock it. The cast could certainly make it impressive and intense. But standing back from it as a whole, it's nothing particularly interesting.
