Insidious: The Last Key (2018)
103 min., rated PG-13.
“Insidious: Chapter 3” but right before 2011’s “Insidious” and 2013’s “Insidious: Chapter 2.” While the sleeper original and its pretty effective sequel (both directed by James Wan), as well as the even-more-effective prequel (directed by Leigh Whannell), all felt of a piece and seemed to have found a proper place to end, “Insidious: The Last Key” is undeniably the weakest of this scary, immensely fun quadrilogy. It fares well as an emotional journey for Elise, but as a horror film, it feels more generic and plodding, waiting for the next scare to come. The great Shaye notwithstanding, “Insidious: The Last Key” tests the devotion of even diehard fans.
"Detention") and Caitlin Gerard (2012's "Smiley") each get their own moments of peril to be placed in and lend some assistance to their aunt, but they are mainly horror-movie pawns.
