I think Universal really tries to listen to guest feedback. They know most people didn’t like the second stranger things house.
The house for this year they will be very careful with to make sure it’s a much better experience than the last two. I think it will be the best house out of the three especially because Vecna is an easier villain to craft a house for.
There are several scenes with Vecna that were terrifying and with the absence of demogorgans, universal can’t reuse props from previous years (like the did with the second house).
