Insidious The Last Key takes us to the childhood of Elise, really painting a portrait of where her inner fortitude and mental power stem from. This film shows us the intense trials she faced as a little girl whose spiritual abilities frightened others. Elise didn't live a normal mundane childhood and become psychic, she was always this way--it helps viewers appreciate why her confidence runs deep, and why she is willing to help others at risk to herself.
Different from the other Insidious films, The Last Key is just as dark, frightening to watch alone at night, and visually mesmerizing. There is a great deal of truth in this movie which fans will connect with--the pain of being different, isolated, surviving a traumatic past, and the ability to find strength in one's own truths, weaknesses, and growing skills. It is Elise's story about not just facing the terrors in "The Further," but facing her past.
Insidious The Last Key, like the other films, has overlapping storylines which connect it with the previous films, creating a greater dramatic experience, and realism--much like our own lives being a domino effect of actions and reactions on various planes of existence. All things are interconnected, and what happens in "The Further" affects the everyday world in which Elise, Tucker, and Specs exist.
I am a fan of Insidious The Last Key. I hear an Insidious 5 film is in the works, and I hope there will be even more! If you're an Insidious fan or James Wan fan, this is a must see!
