What, in your opinion, is the most overused room/scene used in haunted houses today?
I wish I could answer this, but I've only worked in one haunted house in my life, and we don't exactly have different themed rooms. They may be designed for different scares, but the entire attraction is built to look like a mix between a Victorian mansion and a decrepit old shack. If I had to guess, though, I would probably say the strobe light rooms are overdone.
