Ellison Oswalt (Ethan Hawke) is a true crime writer that was successful in his debut with the book "Blood in Kentucky", but also has failed on his next works. He moves with his wife Tracy (Juliet Rylance), his son Trevor (Michael Hall D'Addario) and his daughter Ashley (Clare Foley) to a house in King Count that belonged to the Stevenson family expecting to write a best-seller. Ellison does not tell to Tracy that the place was a crime-scene, where four members of the Stevenson family were hanged on the backyard and the girl Stephanie had gone missing.
Ellison begins his research about the murder and soon he finds a box with super 8 home videos in the attic. He watches the movies and discovers other murder cases that might be connected to other crimes. He befriends the local Deputy (James Ransone), who is his fan, and gets additional information about the cases. He also sees a creepy man in the footages and symbols painted on the wall. He contacts the specialist Professor Jonas that tells him about the cult to the legendary Bughuul. Meanwhile, Ellison and his family are frightened by spooky events in the house. Ellison decides to quit his research and return to his house, but soon he receives a phone call from the Deputy telling what are in common in the crimes.
"Sinister" is a dark and spooky horror movie with a creepy ghost story. The plot is developed in slow pace but I startled many times with the weird situations. This is the first time that I see Ethan Hawke working in this genre and he has a convincing performance. The scary and gore conclusion offers a chance for a sequel that I hope that it does not happen. My vote is seven.
Title (Brazil): "A Entidade" ("The Entity")
