Sounds likely. I don’t have any reason to doubt him. I’m aware of the themes in Hellraiser. Seen the movies, read the book. (The first one, anyway.) It’s pretty obvious. It’s not subtle. The whole “person seeks out extremes of sensation and winds up with much more than they bargained for” is a recurring trope.

That doesn’t change the fact that the bad guys are dressed kinky, and no, they don’t use safe words. It’s supposed to freak you out. In fact, I would even say that Hellraiser is one of the worst in that regard.
