Reading the reviews from the many, it seems people didn't like the film because they didn't like the characters. Particularly judging the victims. It paints the awful picture of our modern day society, still blaming the victims.
Not all films are fluffy and require 'smart' victims, which what many of the negative reviewers are basically saying. All the while missing the entire point of the film. Perhaps this films speaks to much to reality, or that it's too real for those negative reviewers?
The performances were solid. There were a few technical things that didn't make much sense in regards to security. Perhaps it was an amateur basic install?
It's an original script. Touching on several issues all at once. I felt it was quite clever.
It's not a happy film by any means. It's dark and quite sad.
While the ending wasn't very climatic persay, it was satisfying.
