After having previously appeared in the first three films as a parapsychologist that helps the main characters solve their supernatural problems, Elise Rainier (Lin Shaye) gets the spotlight in this movie.

Helmed by Adam Robitel and penned by Leigh Whannell, The Last Key follows Elise, who returns to the house where she grew up in after receiving a call from Ted Garza (Kirk Acevedo), the house’s new owner. Ted says something has disturbed him and that there is a room he is too afraid to open.

Elise, who visits the house with her sidekicks Specs (Leigh Whannell) and Tucker (Angus Sampson), later finds out that the evil entity that has haunted the house is connected to her past and she must hurry to solve her unfinished business before the devil harms her family and friends.

The Last Key is formulaic in how it scares the audience. Some scenes, which are supposed to make viewers jump in their seats, are rather predictable due to the slow pacing.

Robitel includes comic relief in the film, especially between Specs and Tucker, a pair that successfully makes people laugh, although perhaps too much for a horror film.

Nevertheless, for those who have yet to watch the first three Insidious films, the movie can still be enjoyed, even without knowing their plots.

Insidious: The Last Key is scheduled to hit cinemas across Indonesia on Jan. 6. (kes)
