Prepare to see Regan MacNeil at her worst (again) when you experience the return of Universal's immersive take on The Exorcist. The masterminds behind Halloween Horror Nights built the exact facade of the house from the movie, so it's almost as if you're stepping inside the movie's poster as you enter the maze. From there, it only gets more visceral (think: the smell of vomit — yes, really) as you endure room after room of different Regans painfully writhing around on beds in various states of possession. The first few Regans are subdued or animatronic, so when a real-live version of her finally leaps out at you, it's hard not to feel your heart shoot into your throat.
