Insidious: The Last Key once again levels its focus on demon specialist Elise Rainier as she investigates paranormal phenomena — with a heavy emphasis on key imagery this time around.
Like Insidious: Chapter 3, The Last Key is a prequel to the stories involving Elise and the Lambert family, meaning the events of this film will likely go a long way towards informing and developing the woman who eventually shows up in the first Insidious film.
However, unlike previous entries in the franchise, The Last Key will specifically focus its story on Elise’s own life as she dives into a horrific mystery within her childhood home.
Aside from that, the film just looks utterly terrifying.
