You shouldn't expect much of this movie. Sinister 2 is trying to bring back the elements from the prequel, like the creepy tapes but the implementation didn't succeed. The whole story is weak, flimsy and recycled. The child actors were really bad and the adult actors didn't do well also. If you want you can watch it to complete the sinister series or to see more disturbing videotapes from Bughuul.
Synopsis - SPOILER ALERT
The same story with a different family. Courtney Collins (Shannyn Sossamon) moves with her two children Dylan (Robert Daniel Sloan) and Zach (Dartanian Sloan) in an empty house after she broke up with her abusive husband Clint (Lea Coco). The little nine-year-old Dylan is plagued by nightmares and sees other children including Milo (Lucas Jade Zumann), who lures him into the basement to watch mysterious tapes on a Super-8-projector, where different families were killed. The situation is getting worse after his little brother Zach found out about it and starts to beat his brother because he is jealous and wants to be better than him. What both do not know, is that the children work for the Bughuul (Nicholas King) and entice new children to kill their parents and siblings. After the incidents of the first movie the former deputy So & So (James Ransone) began to investigate in these cases and finds out about the Bughuul and now he tries to save the family from death.
The new director of this movie is Ciaran Foy, who worked on the series The Haunting in Hill House. Scott Derrickson, who directed the first movie worked as a writer in this part.
