I had seen this a few years ago but decided to watch it again after seeing Birdbox. There is a dystopian heaviness that hangs over each of those movies. This one is not exactly a thriller. It is a gut wrenching sci-fi love story. It is also a lyrical commentary on humanity. The music is lush, narration is poetic. The plot is nightmarish with a jarring edge of realism. It is not especially fast paced so those who want crossbows and zombie blood will not like it. This is the "thinking man's" end of the world type flick.
