The parapsychologist Dr. Elise Rainier has nightmares with her childhood in New Mexico, where she lived with her brother Christian, her supportive mother Audrey and her father Gerald, who frequently beats her when she claims that she sees ghosts everywhere in the house. When the client Ted Garza calls Elise to ask for help since he is haunted since he moved to a house in New Mexico, Elise refuses the request since the address is the same house where she spent her childhood. However she changes her mind and accepts the job, and travels with her assistants Specs and Tucker to New Mexico where they will discover an evil entity in the house.

Did You Know?


The second instalment in the Insidious franchise to feature a demon, following Insidious (2010). See more »


(at around 41 mins) It's clear from the narrative that Elise and her brother have not seen one another for at least five decades. How or why they would recognize one another despite not having remained in touch over that period of time is never explained. This is especially true as they have changed radically from the way that they looked in their youth. See more »

Fear comes home
23 October 2018 | by TheLittleSongbirdSee all my reviews

It took me a while to watch 'Insidious' and its follow ups, with so much going on with my studies and commitments and with an ever growing watch and review list. Decided to finally watch them all, with the intent of reviewing the latest film as part of my quest to see as many 2018 films as possible and wanting to see how it compared with the previous outings. Also with an appreciation, if not quite undying love, for horror.

Although there are people who understandably dislike it, found myself enjoying the first 'Insidious'. It didn't blow me away but it was well made and genuinely scary. So watched 'Insidious: Chapter 2' hoping it would be as good. 'Insidious: Chapter 2' for me was watchable but not as good, and feel the same about the third instalment and this latest, and perhaps last, one. There are big drawbacks but there are good things here too.

First and foremost, 'Insidious: The Last Key' looks great, especially for horror films released in recent years (too many of which have looked like they were made on the schlocky cheap). It looks slick and stylish while having a spooky setting and suitably nightmarish lighting. The effects are also suitably eerie. Although a bit too obvious in spots, the music is hauntingly atmospheric.

Direction at times is competent and there are some genuine shocks and some creepy scares and dread. Some nice restraint here and there.

Acting is not bad at all, with the best assets being Lin Shaye's ghoulishly gusto-filled performance, something that was consistent throughout the whole franchise, and the interesting development and character of Elise.

Regrettably, 'Insidious: The Last Key' has drawbacks. It does lack tension and suspense all the way through and other scares are predictable, more silly than creepy and felt like throwing in as many horror elements as one can muster regardless of originality, parts feel recycled too. Some of the film is on the dull side, with it unlike the first three films taking the restraint of some of the early parts too far, which was more of a problem with the scares being infrequent and not as effective as before. The last third comes over as too silly and over-the-top, the suspense and dread diminishing and the lack of sense and stupidity increasing.

The latter parts of the previous three films also went over-the-top after being restrained at first, but not to this extent. Capped off by an ending that's cheesy, ridiculous and anti-climactic. There is very little new here or much to set it apart from what was seen before, being even more derivative than the first three entries which lacked originality too but not like this.

Script lacks tautness and has some humour that felt misplaced, overdone and jarring with everything else. Any attempts at twists were generally not surprising and ended up not being very plausible. Sense is not a strong suit here, the latter stages being at times convoluted.

In conclusion, definitely worth a watch but not one of those rewatchable all over films for me. 5/10 Bethany Cox
