After dinner, here’s a very peculiar dessert: Insidious - 3 (2015).

Insidious according to google is (adj) proceeding in a gradual, subtle way, but with harmful effects. treacherous; crafty. Also,  beguiling but harmful. 

This movie is the third sequel of its famous and successful startups. A horror movie that invests much on  shocking and catching the audiences off guard. The story revolves around some bad spirits that aren't peaceful to wherever they are, and they tend to cause harm to the living. It seems to be an awkward choice of dessert after dinner huh? I’m just into very drastic movie genre selections lately.

Director: Leigh Whannell
Stars : Dermot Mulroney, Stefanie Scott, Angus Sampson
Description: A prequel set before the haunting of the Lambert family that reveals how gifted psychic Elise Rainier reluctantly agrees to use her ability to contact the dead in order to help a teenage girl who has been targeted by a dangerous supernatural entity. 

According to commonsensemedia, Parents need to know that Insidious: Chapter 3 is a prequel to Insidious (2010) and Insidious: Chapter 2 (2013), with returning stars Lin Shaye, Angus Sampson, and Leigh Whannell. There's tons of spooky stuff -- mainly well-timed jump-scares, plus images of a scary demon attacking a teen girl and a psychic fighting with the same demon. The teen girl is hit by a car and roughed up quite a bit while wearing casts on both legs. Knives are wielded, but only a little blood is shown. Infrequent language includes one use of "f--king," one "bitch," and a few uses of "ass," plus a middle finger gesture. A teen boy has a crush on the teen heroine, but nothing comes of it. There's a joke about two teen girls being lesbians. Like most horror sequels, it's not as good as the original, but it provides enough tingles that it should be a fairly sizable draw for teen horror hounds.

The aforementioned site adds- On the downside, like the second movie, Insidious: Chapter 3 doesn't have much new to offer, and virtually all of the scares are of the jump-shock variety, with monsters appearing suddenly -- and frequently shrieking as well.
