Planet Earth II: parents' guide

Predators hunt and kill on screen in most episodes: racer snakes seize hatchling iguanas, skuas take penguin chicks, a jaguar kills a caiman, lions hunt a giraffe and a buffalo, and hawks and falcons catch squirrels and pigeons. Some bloody carcasses are visible.

No profanity at all. The narration is calm and educational, and there is no human dialogue to speak of.

No sexual content. Courtship displays, such as dancing birds-of-paradise and male Komodo dragons fighting over mates, are shown, and mating is described in plain scientific terms.

No drinking, smoking or drugs of any kind. This is a wildlife series with almost no people on screen.

Several sequences play like thrillers, especially the island chase of newborn iguanas by swarms of snakes. A mother snow leopard is injured defending her cub, and disoriented turtle hatchlings wander onto city streets instead of the sea.
