I have no evidence for this besides my idle, crazy speculation, but it does kinda feel like Twin Peaks with that insane dream sequence before the torture scene. Obviously, the torture scene is the finale, there'll be a black gauntlet with "kiri kiri kiri" playing over it at the end.
Beginning scene and facade can be the Bag-apartment with a vomiting Asami, then off to the ballet studio with a facade, headless corpse, and Asami; and the Restaurant with the chopped pieces and tongue and Asami; then the finale at the house. There's the dead dog from Halloween 4, the staircase from Trick R Treat, Asami with a syringe and spray-bottle, and maybe dead Rokyo standing in the window.
As long as they cut out the, ahem, stepfather parts, it should be golden.
