If you know BBC productions like f.e. Blue Planet I & II you already know the kind of work and dedication that went into those shows. Human Planet is no exception. But, as the title says, it is about humans and not about wild life. It shows how people have adapted to live in diferent environments. And that means, above all, hunting. So a large part of this show deals with hunting, with killing animals to survive. If you don't like that you should probably skip this. I know that all of this is part of life and that those people really hunt to live. That they don't threaten animal population. Nevertheless I don't think it is nessessary to show multiple hunting scenes in every episode but that is up to ones personal taste. But it also shows what humans are cabable off doing with what little means they have at their disposal.
Still, from all the BBC nature/wild life documentaries I have seen so far this is my least favorite.
