RE: [Maze] Slaughter House (2010 - Current)
I think we all have nostalgia for specific mazes and regret when they are replaced. But a haunt attraction, more than a thrill ride, has a fairly short shelf life, in my opinion.
In addition to everything Zachary said about the psychology of the houses, I would add that when the parks create new mazes, they have the opportunity to experiment with different approaches and technologies. I miss some of the early houses from HOS, for example, but both Lumberhack and Cornered were completely different from anything else the park has done at the event in years. Introducing new stories, approaches, technologies, etc adds variety and keeps the haunts interesting.
I find myself losing interest, even at Halloween Horror Nights, when every maze I enter relies on the same types of scares. I personally don't think Slaughter House brings anything unique or fresh to the table. I'd much rather see KD introduce a completely new house with possibly a more modern or experimental structure and theme.
If that makes sense?
