They want their message heard and attention spans are short. Sadly, but accurately, they decided this was a way to hold people's attention. A sickly, weakly conceived meme. You could argue this is black comedy, but being quite a fan of actual black comedy myself (the movie Brazil, anyone?) - I would say labeling this video as such merely gives the genre a bad name. In other words it's not funny, black humor or not, and I don't think I'm projecting too much onto the video to suggest an overt hostility channeled by its creators. But, to come full circle, they did achieve their goals:
1. Hold my interest for x amount of time
2. Get me to hear their message
3. Get me to talk about it
4. Remind me of what 10/10 is being touted as this year
So good for them , I guess
