It’s not a concern about “glorifying” it, it’s a concern about trivializing it. There’s a concern that the presentation of such a sensitive, traumatic topic won’t be presented in an appropriate manner.
Haunted house aren’t exactly capable of nuanced storytelling or characterizations. In the case of Invisible Man, as a property and character, it isn’t the murder or general violence that makes it scary, it’s the manipulative obsession that drives him. His belief that he “owns” our protagonist and the extent he goes to prove it by driving away the people she loves most and making her question reality itself. If you ignore that in the house, you’re saying it isn’t important when it’s actually the only thing that matters. If you present it in the house, then you’re taking a very real, very present, and very horrifying trauma that a number of guests will have experienced and saying, “We find the horror of this experience entertaining.”
This reminds me of my issues with Nightingales in 2011. War isn’t entertaining or a set piece. It’s something that causes very real trauma to thousands. We shouldn’t see a “pandemic” or “plague” house this year because *gestures wildly.* And even those numbers pale when compared to numbers of victims of some form of domestic abuse. With Invisible Man, they either white wash the entire point of the movie (which trivializes the horror of domestic abuse) or they recreate it completely (which trivializes the experience of domestic abuse). Just imagine if a survivor of domestic violence gets cast a victim in the house.
