This is a mini film from YouTube. It is called The Flying Man. A mock story of a Super hero going bonkers. A crazy vigilante who goes on a rampage killing people who have criminal records. Its got bite and it's a creepy look at a totally wacky anti-hero. The faceless man just appears above the city and crowds of people are filming him on their mobiles.
In many ways it is having a pop at what it may be like if a real being with super powers could patrol the skies un-hindered and un-restrained as in comic books.
