Ghosts and demons are expected to rise up on Halloween, and the ones within the haunted house of Jack Neary’s twisted and brutal tragicomedy, Trick or Treat, do not disappoint. The walking dead linger on the staircase while the spirits of deceased relatives, as well as some long-buried secrets, emerge to effectively tear apart a family. Hints of betrayal, mental illness and physical violence pervade the air, so don’t even ask what happened in the basement. Not that Neary’s characters are wearing white sheets, bloody robes or devil horns. No, this is a far scarier and more tragic clan: a passive-aggressive, Irish-American, middle-class family in eastern Massachusetts.
