What a beautifully haunting film this was. An interesting and unique take on the virus type story. It reaches out and grabs you, pulls you in, and with every amazingly cinematic scene, you are hooked. 
The story was intense and very emotional, at least for me anyway. It really allows you to connect with the characters and imagine it happening to you. It took hold of my soul, and was deeply felt. And the score was stunning. 
This is a must see. One of the best films I’ve seen in a long time. Highly, highly recommended.
