I found this movie to be pretty effective in how it's executed. The story is interesting with teenagers able to contact spirits with a mysterious embalmed hand. I really like the idea of holding a mysterious hand to contact spirts and then say "I let you in" so it possessed that person. It really shows how it is a bad idea to do those types of things and how they affect someone. The movie is also a subject matter of grief and obsession with the main character losing her mother and wanting to contact her. It really shows how far someone can do in order to talk to a loved one again. The movie also works as a psychological horror with the main character struggling with her grief and obsession towards her mother and that hand throughout. It also affects her mental health and cause her to do some extreme stuff later on in the movie. The ending itself is pretty good on how it ends.
