Don't believe the rating, this is IMDB remember

IMDB is the worst pile of *beep* website for any medium or art confounded. Lame blockbuster or even tame serie are overrated, but little gems like ABCs of Death or Little Deaths are completely under-rated.

In this anthology, there are three horror movies with an original, grim take.

The first one as a surprising although weak twist
The second one has an interesting story and development
The third one is brilliant almost at the level of the best modern/pop drama directors.
