"Unfriended" is a low-budget horror movie uniquely tailored to the early 21st Century (it certainly couldn't have been made, say, twenty years ago).The film takes place entirely on a teenage girl 's computer screen, as she (Heather Sossaman) and four of her cyber-linked friends (Moses Jacob Storm, Renee Olstead, Jacob Wysocki, Will Peltz) are terrorized by a mysterious sixth presence that has mysteriously joined them in their cyber chat and who may well be the avenging spirit of a classmate who recently committed suicide as a result of cyber bullying.
