Gonna re-post an idea for an original I had on HNN:
HR Bloodengutz Presents: Pop Torture
~10-15 years after the events of the first house, WKNB in Carey, OH has moved on from holiday horror films and now makes scary music videos, specifically for different decades of pop culture. When a certain former TV host escapes from prison, he again takes the studio hostage. I'm not quite sure in what ways the captives would be tortured in the transition rooms, but the house would go through dark versions of stereotypes of pop culture for each decade from the '20s-'90s. Basically a dark Pop Century. Would fit the "throwback" theme they seem to be going for.
Thoughts? Specifically, ideas for the "torture" of each decade? The '60s could involve pouring literal acid, hehe.
