did you watch a cam version?Boy Kills World
This was a bit of a surprise, think of a mix between The Hunger Games, a bit of John Wick, add some Running Man and a bit of The Purge to spice things up. The boy of the film watches his mother and sister get killed by Hilda Van Der Coy, whose family rules over the city, and it leaves him deaf and dumb. He's picked up by the mysterious Shaman who trains him to become an "instrument of death" to avenge his family.
Plenty of action fight scenes and a few gruesome deaths later, a slight 'twist' is revealed about 30 minutes before the movie ends, you may or may not seeing it coming, overall, I'd say a 3/5 just for the action sequences and fight choreography.
