These are the movies inspiring haunts at the Halloween Horror Nights at Universal in 2019.
I did not see the stranger things house.
The Pandora's Box house did some fun stuff with camouflaging actors in a section to look like the walls. The were a lot of spots where it was unclear which things were going to move which was fun.
The Holidays in Hell house was pretty silly, which was fun. There were people in Turkey costumes for Thanksgiving which made most of my group laugh.
Playing Crypt TV outside the houses was a great idea from Universal.
