I don't believe spoilers can completely ruin a genuinely good movie, but when it comes to horror films, initial shock is given a lot of value. So I would tell you to go see the movie before reading anything about it, as that's really the best way for something like this to be seen. END OF SPOILER WARNING
So I saw hereditary last night. I was pretty hyped for it since genuinely good horror movies are a dime a dozen, and I can confidently say it didn't dissapoint, just that it accomplished this in very unexpected ways. It turned out to be way more surreal/absurd than I expected it to be, which is a good thing because that's the horror I appreciate the most. When a movie can successfully contrast moments of fear, shock, grief, etc with ridiculous moments bordering on comedy, it makes the horror stuff so much more unsettling and unexpected. This movie played it pretty straight throughout, but there are moments of dry-comedy peppered in there that are used in the way I described above to great effect (especially near the ending).
I know the movie has been pretty divisive with audiences, so it would be nice to hear from some people with both positive/negative perspectives. Ultimately, in my mind, the marketing did a disservice and conned people into thinking hereditary was something it isn't. It's also very different from movies like the conjuring, as those films actually end in a happy, easily understood, easily digestible way, where this film reaaaaaallllly does not.
Side note: what was up with the girl clicking? That's really the only thing that totally confused me in a way where I thought "is this necessary?". Now that I think about it maybe it was to show, definitively, that Charlie really did possess Peter in the end, while allowing for the moment to be played in silence/without much explanation/questioning between characters. That's a decent enough explanation, but a narrative explanation would have been appreciated
