This was better than Hereditary

Wow, I wish I could see what you got from this film, because I just found it really boring and not scary at all. I'm going through something in my life now where the ending should've hit me harder (as you alluded to) and it just didn't at all. Was very meh overall for me.

Sorry. Just watched it. Was well done in terms of atmosphere & score, yes. But overall seemed to be a meditation on the dangers of black mold. Which we already know is dangerous. I had high hopes when they find the note, early on, that says "don't follow it". But that led nowhere. And Sam getting lost in an other-dimensional version of the house, also interesting. But if it was just hallucination on her part, no so much.

What was the deal with the great-grandfather? Was the idea that he was infected by the mold, left to suffer & rot. Said mold later brought to the house via the windows? Okay. So it lay dormant for all the years Kay & Edna's husband lived there, only striking when Edna was alone?

Did like the ending where Kay found herself unable to walk away even though the black thing was plainly no longer her mother. And Sam couldn't leave Kay. References back to her comment about mom changing your nappies, then you change mom's.

Still, nothing at all like Hereditary. I mean, all we the viewers have is speculation as to what happened & why. Seems like weak storytelling.
