I think we look for different things in horror. Some elements resonate more with us than others. Mike F’s creations work for me because of his willingness to invest in his characters, therefore making the horror more real. As many have noted, the demons, at the end of the day, are humans, not ghouls.
Some horror fans are more into jump scares and gore, while others prefer a good mix of different elements. It’s rare to come across horror films/series that come close to appealing to different types of horror fans. I think Hill House comes close, but perhaps less so for Bly. That doesn’t mean it’s inferior though - and I’m not suggesting that some here are suggesting that it is. It’s just a different type of horror.
I look forward to season 3.
