Mary on paper at least had plenty of potential and with a recent Academy Award winner at the helm in Gary Oldman, this was an all around disappointing film with poor editing and weak plot and characters.
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.
