Insidious: The Last Key is by no means terrible but just another ho-hum and inoffensively bland entry in a franchise that at its height were merely okay, but is highlighted by Lin Shaye being a badass once again.
Insidious: Chapter 3 is a competently well made flick with some good scares and decent performances from the main cast with Lin Shaye being a welcome member getting more back story for her character. The Blu-ray released by Sony is rather basic with good video/audio transfers and a forgettable selection of bonus material.
