You do understand that the TV shows and movies have special effects that they can hide from the cameras that could not be used in a three dimension house, right? Stuff like CGI, animatronics, etc? Practical effects, especially ones that can be replicated every 30secons for 8 hours a night for 40+ days are almost non-existant.
If you get a re-skinned cabbage patch kid on a stick jumping out of booholes, think you'll be happier? Maybe a Teddy Ruxpin with it's mouth moving but not matching up to the audio cues?
BTW - spoiler alert, the castle facades you've seen before weren't real castles. In fact, they were only about 30 feet tall. And that Mind Flayer that in the show it towered over a town, it wasn't that big.
Houses require a suspension of disbelief. Sorta like walking out of 90 degree weather with 99% humidity for a heat index of 120 and walking into a winter set house.
