Insidious: The Last Key (2018, dir. Adam Robitel)

Elise Rainier returns to her childhood home to face her fears. The fourth in the Insidious franchise is a prequel which loops back to part one.  For series fans only, but well-enough handled in its jumpscares and creepy moments, plus one great idea, decently handled.

Cooties (2014, dir. Cary Murnion and Jonathan Milott)

Teachers are held under siege when their summer-school pupils contract a deadly virus. Serviceable horror-comedy which gets some mileage out of a game cast and script, and from its gleeful approach to child-centric gore.

Insidious: Chapter 3 (2015, dir. Leigh Whannell)

Part 3 is a prequel, offering backstory on Elise, and her team-up with Specs and Tucker, plus another demonic yarn. Lots of jump scares, handled well enough if you like this sort of thing, with series screenwriter/actor Whannell now elevated to director.

Insidious: Chapter 2 (2013, dir. James Wan)

The Lambert family aren’t free from their demons. Direct continuation from the first movie, deftly interweaving the events of that with this. Jumpscares galore in this efficient carnival sideshow flick, which delights in well-crafted boo! moments.
