Most of the show does not include Violence or Gore. Then you get to episode 10 and the level of violence moves to at least moderate. Footage of people hitting, kicking and throwing rocks is shown. Also two people are shown on the ground unconscious and it is not made clear if these people are alive or not.
In Season 1 Episode 10 Hooligans. People are seen fighting, kicking, punching, and stamping on each other heads. Not extremely graphic but may disturb some younger viewers.
