Was it the best movie I've ever seen? No.
It felt a little long and drawn out, but production quality and acting was strong. Even the storyline ended up coming full circle and giving the audience resolution and answers to the questions which I really appreciated. Usually this type of movie will end up leaving you to feel confused or they'll leave you on a cliff hanger. I appreciate that things were explained and that the story made sense in the end.
I loved the creepy/eerie shots. Like when they would stare at the black hole in the fireplace or staring into the black empty dresser. I feel like the storyline compares to movies like Hide and Seek (2005) or The Watcher (2022), but it had a very dark, unsettling, eerie feeling that compared to The Witch (2015) and Hereditary (2018). It's nowhere near as scary as either or those movies, but the music and camera work had similarities.
If you enjoy thriller or horror, then I think it's worth a try. Especially with the lack of horror movies and thrillers on the market right now.
