I mean. That is fine, for then. A majority of people playing then had seen and experienced gothic horror, or classic horror in the normal pace of consuming media. With a widening selection of horror amongst a throng of genre's, where the current trend doesn't seem to be Gothic horror, this probably won't be the case. Yeah. There will be some younger people out there that found Gothic horror and love it, and many who are aware of it at least. Inspired and wanted to D&D in that particular horror genre? Unlikely.
And yes. People changed, and continue to change. How they consume media changes, trends change, world views change, and what is acceptable changes.
