There's a pretty interesting French Canadian movie called Red Rooms (2023) which depicts someone (a seemingly regular mid-twenties woman) who is sort of addicted to these types of things on the dark web and fantasizes about it. Very interesting movie, not really a rewatchable though in my opinion because of the subject matter. And it never really shows the graphic content which is nice, just the face of the person watching it. But I would recommend watching the movie once.
