I’ve said this before, but I have a suspicion that a large part of why Scarefest is so panned among enthusiasts these days is down to overfamiliarity rather than the attractions themselves actually being poor quality.
Scare attractions are inherently less “rerideable” than something like, say, a roller coaster due to their reliance on the element of surprise, so enthusiasts who’ve experienced Alton Towers’ current scare attractions multiple times each year for multiple years in a row are bound to get a bit bored of the offering.
But the thing to remember is that most people will not be visiting Scarefest annually, or at very least will not visit Scarefest at the frequency the average Alton Towers enthusiast does. Many people will have never visited Scarefest before, and many others will not have visited for a number of years. To these people, the Alton Towers offering will still pack a lot of novelty and still punch in the same way it always did. Not everyone is an enthusiast who’s been to Scarefest every year and gone long past the point of being bored with Alton’s current scare attractions. Many people will walk into Scarefest as first time visitors or visitors who haven’t been for a few years and will still experience wide-eyed wonder and surprise at Alton Towers’ offering.
As for why Scarefest feels “stale” and independent scare events like Tulley’s and Fear at Avon Valley don’t despite also not changing the mazes, I feel that that again goes back to overfamiliarity. It’s likely that these independent scare parks have far less people who are overly familiar with them in the way that they are maybe overly familiar with Alton Towers’ offering. I could be wrong here, as I kind of check out of the vlogging and trip scene during scare season to an extent, but you don’t seem to get enthusiasts going to Tulley’s or Xtreme Scream Park or Fear at Avon Valley annually in nearly the same quantity as you get enthusiasts going to Scarefest annually.
