Ostensibly a prequel to the inexplicable 1979 hit The Amityville Horror, A2 tells the story of the Montelli family, who move into the infamous house of evil. The movie wants us to believe that Ultimate Evil took a fine, upstanding middle class family and turned them into dysfunctional, sexually abusive assholes, but the Montellis seem to have at least brought the abusive asshole part in with them. After engaging in a few petty poltergeistesque shenanigans, Ultimate Evil decides to take possession of the mind and body of the eldest Montelli son, Sonny. (It wasn’t hard. Both his mind and body were unclaimed at the time.) Soon after, Sonny’s sexually abusing his teenaged sister and acting slightly creepier en route to murdering his entire family. After the murders, a priest swings into the plot to try to perform an exorcism, which, for reasons known only to the screenwriters, has to be performed at the famous Amityville house. A few scenes of exorcism-fu later, Sonny’s dispossessed (though facing five consecutive life terms for his murders), and the priest now houses the soul of Ultimate Evil, though in the plus column that makes him the owner of a lovely three-story Dutch Colonial with a boathouse.
