It's very clear from the current rating and reviews on here that a LOT of people didn't get this movie. It certainly doesn't spoon feed anything to the audience. If you're looking for something that makes perfect sense and leaves you with zero questions, this is not the film for you.
Despite a small cast and a pretty minimal plot, the actors did a beautiful job conveying their emotions throughout. Hope, despair, determination, love for each other.
The ending brought me to tears, and while I can see why this movie may not have mass appeal, I am baffled that someone could watch this and not feel even slightly moved.
