Friend Request

Friend Request (released internationally as Unfriend) is a 2016 German English-language supernatural psychological horror film directed by Simon Verhoeven.
Plot.
Laura Woodson (Alycia Debnam-Carey) is a popular college student with over 800 friends on Facebook. She lives with Olivia Mathison (Brit Morgan), Isabelle, and Gustavo Garcia (Sean Marquette), Isabelle's boyfriend. She is close friends with Kobe (Connor Paolo) and is dating Tyler McCormick (William Moseley).
Laura receives a friend request from her classmate Marina Mills. Noticing she has no friends, she accepts and the two begin hanging out, but she is uncomfortable with Marina's obsessive behavior and sees that her Facebook profile is full of disturbing posts. Marina wants to attend Laura's birthday dinner but Laura lies and says only she and Tyler are going out. That night, Marina sees pictures of Laura and her friends on Facebook, and angrily confronts her the next day. During their quarrel, Laura accidentally reveals Marina's bald spot, a result of hair pulling disorder. She then unfriends Marina on Facebook.
The next morning, it is announced that Marina committed suicide. Laura feels responsible but tries to forget about it until Marina uploads a video showing her burning a sketch of Laura before hanging herself. The video is somehow posted on Laura's own page and she is unable to remove it or delete her account. Marina adds Gustavo as a friend. He is then terrorized by a demonic spirit and has his face smashed by an invisible entity. Isabelle discovers him and is sent to the hospital. A video of Gustavo's apparent suicide is posted on Laura's page and once again, she is unable to delete it.
Laura's friends and family begin to turn against her. Kobe and Laura break into Marina's dorm room and find an old class photograph from an orphanage. Laura visits the orphanage and discovers Marina's real last name is Nedifar, and she was tormented by two boys when she was younger. The boys were murdered, with their faces mutilated and swarmed by black wasps, the same way Gustavo died. Her mother had been part of a commune, rumored to be a demonic cult, until someone set it on fire. Her mother, then pregnant, was horribly burned and doctors did a C-section to get Marina out of her burnt body. Kobe does research on black mirrors, which they keep seeing, and learns that they were mostly used by witches. 
Isabelle becomes Marina's next victim. A video of her killing herself is posted on Laura's page. Olivia is attacked and killed next. Laura and Kobe go in search of the place where Marina committed suicide to destroy the black mirror she died in front of, as that is what she used to become an evil spirit to torment Laura. Kobe, realizing he is the next victim, becomes deranged, and stabs Laura, hoping to kill her and save himself.
She escapes and learns that Marina killed herself in a nearby factory. Tyler finds Laura, but Kobe kills him. Before he can kill Laura, Kobe is killed by the swarm of wasps. Laura sees an apparition of the two mutilated men (the boys that bullied Marina in the orphanage) and yells at Marina, asking what she wants. The spirit of a younger Marina appears and says that she just wanted to be friends. Laura is then lunged at by a demonic Marina.
In the epilogue, Laura, now possessed by Marina, looks at a few girls the same way that Marina looked at Laura in the beginning.

Critical response.

Audiences polled by CinemaScore gave the film an average grade of "C+" on an A+ to F scale.
Frank Scheck of "The Hollywood Reporter" praised the film for being "visually stylish and imaginative" but criticised it for becoming less interesting as the film went on. Jessica Kiang of "Variety" was impressed by the practical effects, but criticised the way the film had little to do with the "technology that it ostensibly exists to critique". Ally Wybrew of "Empire" gave the film 3 out of 5 stars, praising Debnam-Carey, who "[stood] out [amongst] otherwise mediocre performances" in contrast to the poorly written character of Marina. Wybrew went on to criticise the clunky lines, overenthusiastic score, and the protracted final act.
