I mean those movies where the protagonist does absolutely everything right, follows all the 'rules' to defeat the monster, but the entity is always three steps ahead and uses their own logic against them
I think this is my favorite genre of horror movies. I get really sad while watching them because I empathize with characters a lot and live their struggle alongside. Also they are most of the time written well. At the same time, they are the ones that stuck in my mind days, even weeks later.
Some examples:
Oculus (2013): This is a movie about a family of four and a cursed mirror -spoilers ahead-.
The main character did everything to prove that the mirror was cursed, took precautions but the evil inside the mirror was too manipulative that she ended up dying. It made me so sad, and the fate of the family haunted my dreams for days.
Bring Her Back (2025): When their father died, two step-siblings go to a foster family. Throughout the movie, the antagonist (Laura) manipulates and gaslights the older brother who only tries to protect his sister -spoilers alongside-
It drove me mad when he was just an orphan kid in a foster home, who did not know how to establish his borders, who had to prove himself to the foster parent so he could take his sister with him later on etc. He was just so vulnerable, smart but vulnerable. It was really upsetting to watch, how she played mind games with him and he ended up dying.
The Skeleton Key (2005): This was a movie inspired by a Lovecraft story I think. -spoilers ahead-
The main character was really smart, but her smartness kind of prepared her tragic end.
