Things quickly get out of hand at a Polish wedding when the groom appears to have been possessed by a spirit from the past. Adapted from Piotr Rowicki’s 2008 stage play “Adherence,” Marcin Wrona’s final film is a ghost story that takes the Jewish myth of the dybbuk and commingles it with strong nods to Kubrick’s The Shining, including the use of a Penderecki score. “The thematics give Demon meat, make it a great film, but it’s the filmmaking that makes Demon a great movie to watch.” – Devin Faraci, Birth. Movies. Death.
