I think you’re on to something there. You’d be amazed at how many people I know that go to HHN (or as they would call it, “Hollywood Fright Nights” or the “Fright Fest at Universal”) and will only do rides and do one maze. That makes zero sense to me, but there are many people that go who feel obligated to go to a scary event but want a break from the “freaky stuff”. They make up a good chunk of people.I honestly believe that part of the appeal of Jabba at HHN is that it serves as a break from the horror atmosphere. As weird as it sounds, a lot of the general public going to the event don't love being scared so they'd jump at the chance to do something that they know is safe.
There's also the idea that most of the general public don't notice or flat out don't care that the show isn't "horror" enough. They go in expecting a modern dance show, and that's what they get. As much as I would love a dark, vaudevillian variety show, that would be such a hard sell to the general public.
I know several people who went in a group of like ten people last year. They did early entry and did Mummy first, Transformers, went through Holidayz, then Purge. They wanted to do ST, but after their two rides, they were like, “Nah, line’s too long.” Then they did Simpsons and Tram and then left because it was “too freaky” for them. I was hardcore judging them for only doing the worst mazes.
So yeah, you’d be surprised how many people go that are apathetic or don’t even like horror!
