A really beautiful, and thought-provoking movie. If you do watch it, please research the deeper meaning behind this movie. Even if it's just the FoundFlix video on YouTube or something.
After I finished the movie the first time, I didn't get it. I was confused. After sitting and unpacking the movie along with reading several interpretations, I brought my own interpretation to the movie and watched it again. Don't take it literally, and don't expect something necessarily "scary" in the usual horror sense.
Please, try to bring your perspective and life experiences to it. You'll appreciate it more that way.
It's incredibly profound.
