Nobody will care how well executed the mazes are if they're not even enticed to go through the front gate by what's being offerred. This event is getting more and more expensive and the crowds are getting harder and harder to please. Hollywood has conditioned its fans into wanting IPs and it's their own dang fault for pushing that upon them in the first place. At this point, everyone knows the scare tactics anyway. Everyone knows you're just going to be conga lined through every maze packed like sardines. Everyone knows every time you go into the dark, something loud and bright will pop out.
We talk a lot about the death of HHN on these forums and how it's getting worse and worse and it'll just flop. All the years before, that was silly because of the momentum it had going. This year has no momentum from the last 2 years and there's no properties this year to build it even further. Everyone here talked about Ghostbusters like it was going to be the savior of the event and the GP reacted the complete opposite to that announcement.
This is the first time in more than a decade that I can myself say, that yes, HHN is on the verge of flopping with this upcoming year if that's all it has in it's arsenal. If this year doesn't bring them in and doesn't hit a homerun creatively (and even if it DOES, you'll still mostly have an empty park), then in 2020 we're looking at a deadzone even if the IPs are good because it'll just be "oh yeah, it was that expensive place that used to be cool but then it was always the same scares and they never had Freddy or Jason, who cares, let's just go to Knotts instead -- at least it's cheap and they try something new, plus they have rides lulz bye."
