Insidious: The Last Key (also known as Insidious: Chapter 4) is a 2018 horror film directed by Adam Robitel and written by Leigh Whannell. It is also the last chapter in the Insidious series. The film opens in the 1950s and tells about parapsychologist Dr. Elise Rainier (Lin Shaye) childhood who faces her most fearsome and personal haunting in her own home.
Young Elise is beaten and barred up by her father in the basement of an old house. Elise lost her mother in the same basement by supernatural entities. Years later, old Elise travels with her team goofy Specs (Leigh Whannell) and Tucker (Angus Sampson) to the same house where there are reports of paranormal events.
Elise childhood fears continue to haunt her whole life, but she finds herself forced to eventually face the nightmare of her childhood when the current resident of her old home contacts her and begs for help. The phone call reminds Elise of her traumatic past including memories of her younger brother, guilt over her mother’s death, a lost whistle, fearsome ghosts and the devil she allegedly released to unleash as a child.
Now, Elise has to look for the “red door” which she opened when she was a child and get the house spirit-free. In the fight with a demon, Elise faced a truth which changed her perspective towards her evil father. The movie also focuses on a whistle that was given to Elise younger brother by her mother in his childhood. The whistle plays an important role until the end of the film and we want to believe that it has some extraordinary magical powers but the filmmakers do not bother explaining. In the end, Elise returns home to where she has a dream again about a little boy which starts Insidious part one.
The fourth installment of Insidious series grossed $51 million worldwide and received mixed reviews from critics. As always, Lin Shaye continues to offer the best performances in the horror genre. The two men, Specs and Tucker from the last installment, provides some laughs in the middle of horror scenes and says humorous dialogue. If you’re looking for an unsettling horror, spine-chilling thrills, jump scares, goosebumps, you will find it hard to watch the film.
