Let's be transparent right off the bat: this is an advertisement. Created by an organization called Save the Children, this video hopes to show you the impact war has on the lives of children around the world.
The video is trying to utilize the recent trend of "Second-a-Day" videos that show snippets of daily life. Only in this video, those seconds become increasingly dark.
The cause is certainly a noble one, but by the time the little girl is blowing out her birthday candles for the second time, it's hard to say whether this is a video about war or a preview for a zombie apocalypse thriller.
It almost goes without saying, but only watch this video if you're a person who is comfortable watching an 8-year-old's happiness vanish over the course of 90 seconds. Yeesh.
