The song remains the same. Honestly, there has always been gatekeepers and toxicity in the Horror Nights community. I'm not proud to say that I was at some point a HHN snob myself. Thankfully, I grew up and realized everybody enjoys things for different reasons.
I, personally, don't see how the house will jive with the event but it really doesn't matter. Maybe it will maybe it won't. Everyone has their "dud" house that varies from person to person. I will go in, at least, once. If I don't like it, I won't do it again. Simple. No need to get upset.
The point is the event is strong. Always has been. I left it for several years to see what else was out there. Other haunts have their strong points, but nothing has really captured the scale and feel of HHN for me. Now that my kid can go (she loved it last year) we nixed the others and are just doing this one.
A little bummed that it looks like Stranger Things won't be a house (as that is my kids super fandom). But most of the originals seem on point and I'm sure it will be a great time.
