Inside the Insidious franchise, sixtyish parapsychologist Elise Rainier has seen it all. She’s been a flesh-and-blood human being, and, later, she took a turn as something of a ghost. Rainier, you see, was killed off in the second installment of the franchise, perhaps unwisely considering how popular — and integral — is the character played by actress Lin Shaye.
The solution to the problem of how to resurrect Rainier proved simple enough: turn to the prequel format. This outing, The Last Key, marks the second such prequel, coming after Insidious: Chapter 3 in 2015.
In this latest chapter, Elise must return to her creepy childhood home after the present-day occupant reaches out to her about paranormal events taking place in the old house near a prison in New Mexico. Reluctantly, she agrees to come back to see what all the fuss is about. In a series of flashbacks, moviegoers see Elise as a child undergoing an awareness of her paranormal powers. As the grown-up Shaye returns to her childhood environs, it takes no time for a series of shocking events to take hold of the plot.
In addition to Shaye, this Adam Robitel-directed production stars Leigh Whannell, Adam Sampson and Kirk Acevedo. Whannell also penned the script based on characters she created.
Insidious: The Last Key scored a horrific 25 on RottenTomatoes, but it’s likely review-proof given the popularity of the horror genre. The film runs 1 hour 43 minutes and is rated PG-13.
