Poltergeist II: The Other Side (1986)

This effects-heavy installment is the inevitable sequel to one of the more effectively spooky and financially successful horror films of the '80s. The Freeling family is trying to grapple with the devastation wrought by the ghosts and ghouls that destroyed their lives. Steve (Craig T. Nelson), Diane (JoBeth Williams), and their kids, Carol Anne (Heather O'Rourke) and Robbie (Oliver Robins), have been reduced to living in the home of Diane's mother, Jess (Geraldine Fitzgerald) because the insurance company refuses to believe what happened to their house. The Freelings are unfortunately unable to escape patches of unholy ground living in a house that is just as haunted as the last. The evil spirit of the mad cult leader Kane (Julian Beck) has returned in an effort to kidnap Carol Anne. After realizing what's happening, the Freelings call upon the psychic medium Tangina Barrons (Zelda Rubinstein) for help, and are aided by a benevolent Native American spiritualist, Taylor (Will Sampson).
