Intense is a good word. All the more impressive as it is done so simply. This is one that stays with you.
Agreed: I find it hard to believe that the exterior of the creepy house was just a mock up and that it doesn't exist somewhere.
I agree, I got to see this in the theaters with my mom and dad when it came out and the scene where the boy was drowned in the bathtub really hit me.
As far as creepy houses go, I just recently found out thru a Youtube video that the exterior for the house in Fulci's "House By The Cemetery"
was actually up in Maine or Massachusetts ( I forget which one). Pretty neat, I'd say.
