This movie is unnecessarily sadistic. ... The story would have been just as effective without [some of its] scenes of violence, which verge on exploitation.
The quiet stretches actually serve their purpose here, creating a sense of intimacy with the characters as opposed to simply marking time between the shocks.
Insidious: Chapter 3 may be a slight improvement over the previous sequel, but with its continued over-reliance on jump scares and a basic, repetitive plot, it merely becomes another chapter that will leave horror fans unsatisfied.
As middling, somewhat serviceable horror fare, it delivers its own share of jump scares, but whatever visceral effect it might have had wears off the instant the credits begin to roll.
