You know, as an AP, it's a show I often skip (sort of like Lincoln at Disneyland)... you just kind of forget about it. But I had fortunately done it twice in the last year, and story-wise, it still totally holds up. One of the best written theme park shows out there.
At the same time, I was thinking it's getting to be time to upgrade the effects. When it first came out, a lot of people believed it was real smoke. By today's standards, it's pretty obvious right off the bat. I wonder if this is just an effects upgrade.
On a separate note, I made a side case some time ago that Knott's needs a Vekoma Mad House. It would be a very unique attraction (especially on the West Coast), very family friendly, doesn't take up much space, and they could theme it in line with the old Haunted Shack, where the house was built over the "center of gravity". Is that not genius or not? Get on that, Knott's.
