When Ted leads Elise, Tucker and Specs to the bedroom blocked off by all of the books/bibles, he tucks the red one under his arm. In the next shot, it's no longer under his arm as he moves the bookcase. He then puts it under his arm again before opening the door to the room. At no point is he shown setting the book down.

This review of Insidious: The Last Key is spoiler free

** (2/5)

SINCE STARTING IN 2010 the Insidious franchise only had one initial idea from director James Wan and writer Leigh Whannell: it started life as a creepy haunted house movie. And you can probably bet that with all the demons, the different characters and the initial storyline that gets pumped out it always ends in the house in which it spawned. Four movies in and the series doesn't seem to have lost that initial scope, that, we can say is a promising aspect for the wearying supernatural storyline of Insidious: The Last Key it ends at a house. However what happens in the meantime tends to lose pretty much everything else.

The film kicks off with a reasonably well-executed prologue instead of opening with the victim of the haunting here the focus changes hands to the childhood of Parapsychologist Dr. Elise Rainier (Lin Shaye), delving deeper into her personal life and inevitably exploring her darkest fears. The 1950s atmosphere is handled with care, the eerie tone that comes with it is polished and the performances are charming. Then the film shifts to the era of the first instalment, and again she returns with her idiotic psychics to investigate her family home and face off against her most dangerous demon. However that sudden shift it seems everything has pretty much been rubbed off as the clean rug has been pulled from us unveiling a Smorgasbord of constant clichés, tired scares and a rubbery demon which from first glance looks to have lost all inspiration.

Like Insidious: Chapter 3 this is a prequel story (now it's 3, 4, 1 and 2 should you ever feel the need to screen these films in chronologically). But this one is Elise's personal story it delves deeper into her life, and director Adam Robitel (The Taking of Deborah Logan) solidly brings her story to life. The look of fear as she faces her most dangerous demon, the close relationship she has with her duo of psychics (Whannell and Angus Sampson) and the intercutting flashbacks of her early years with her abusive father (Josh Stewart). It's certainly a well-done premise now we're four films in and it's made better with Shaye's always welcome presence. Yet despite the title the film fails to unlock all the ideas at hand and with fewer scares than ever it seems that all the inspiration has been entirely rubbed off, initially losing its spark. Granted Insidious: The Last Key is certainly murky stuff losing its potential over the previous instalments but you have to credit the ambitious casting at putting 74-year-old Shaye at the top. Plus the addition of the emotional plot writes some creative grandeur, yet due to uninspired ideas and tired scares it seems that the ideas have hit their tipping point. VERDICT Shaye's always welcome presence gives her all but after uninspired ideas, a routine storyline, retired scares and lacking inspiration it's clear that the fourth chapter has lost all hope.
