Based on the trailer, I really thought I would not like The Black Phone, as I do not like movies that display adults harming children. However, this movie was really about the connection of siblings and the strength of the human spirit. Also, there was a similar concept that was used in the movie Coraline that was a major storyline in this movie, which was done rather well.
Overall, the cast, the cinematography, and the movie as a whole, was surprisingly great. Oh and I have to admit there was one jump scare that got me, so this one is a 8 out of 10.
