This movie had a high tensed suspense and is a good psychological thriller.
For me the end part where I discover the place of safety is a school for the blind was all the lesson the world needs.
It shows how deeply flawed our perspective of life can be sometimes from our different points of views and you wonder if we are losing our love for each other because of our sight. Perhaps if we could be blind to each others flaws maybe we can survive the evil that eats up our world. Maybe we can learn to judge with our hearts not our sights.
