Where to draw the line with horror

I feel like we would have had a third The Woman In Black film by now if not for the whole “viciously murdering children” bit. That’s always seemed a bit much for a mainstream franchise.

And I say this as someone who has an idea for the next film - it’s the early 1970s and a rock star buys the house because of its reputation, like Jimmy Page with Aleister Crowley’s old digs. Hilarity does not ensue. Might work as a horror one-shot...
