Unsettling, disturbing but to some extent depicts some of the real, dark and true personalities about people. Most disturbing was the way the dog was treated and died. I didn’t understand what was the point of the dog in the whole movie, was it symbolising something...?
One thing the movie is trying to show is the negativity people withholds within them and how it affects them and others (may be dog here) around them adversely.
Only if they all have been more positive and healthy individuals.
