The story is really interesting on how it's told about a patient who has Alzheimer's disease that has something sinster inside of her. It's well built up, and the movie gives a lot of interesting information about the disease throughout. I also like some parts of the movie that documentary purposes for the story.

The creepiness factor is pretty effective on the scares, and the climax is really suspenseful. Also, the ending gives off a spooky vibe to it.

The characters are pretty good throughout and have solid development. Deborah is a patient who has athe disease and goes through a development on her becoming more strange and violent. Sarah is Deborah's daughter, who tries her best to help her mother and do anything to fix her. Harris is a strange character who has a secret about him.

As for the documentary crew, they're mostly mixed. I really like Gavin because he feels realistic and makes a smart decision. Mia and Luis aren't that interesting, but they still support the characters.
