Insidious 2

The ending in the original film left no question, of course there is a sequel.
This sequel from the same director is also a must-see masterpiece, and you MUST watch the original first.
This is film is every bit as terrifying as the first film, so chilling, so many jump scares, you're gonna be covered in goosebumps.
They do an incredible job intertwining the films, but also a totally wild and truly disturbing twist, really great writing from Leigh Whannell who also stars in the film, and goes on to direct the next film.
The score, set, and special effects are great.
There are two prequels and sequel after this, all of which we recommend watching, in order of release.
Fair warning: you may not want to watch this before bed.
Features Patrick Wilson, Rose Byrne, Barbara Hershey, Lin Shaye, Ty Simpkins, Angus Sampson, Leigh Whannell, Danielle Bisutti and others.
Trigger Warning: child abuse.
