It's a general rule of thumb: Beware any horror movie with the words "Last" or "Final" in the title. They're probably lying. In any case, here's the fourth film in the ghostly Insidious franchise. Chronologically speaking, this one takes place after Insidious 3, but before Insidious and Insidious 2. It concentrates on demonologist Elise Rainier (cult actress Lin Shaye) as she goes to New Mexico to investigate the haunted house she grew up in.103 minutes PG-13.
