Maya, as Tina Fey narrates, “gets the scraps. This is what it means to be last in line. ”

Heavy stuff, not that the very young members of Generation ADHD will catch all of it.

But they may be bothered by the violence. Macaque cliques go at it, with thei r vampire fangs flashing and expressive eyebrows expressing rage in attacks designed to up- root Maya’s tribe from Castle Rock and the abandoned ancient Sri Lankan city that they call home.

“Monkey Kingdom” begins cloyingly, with frolicking set to “Hey Hey We’re the Monkees.” The arrival of Kumar, Maya’s monkey-love, prompts a cover of Salt-n-Peppa and En Vogue’s “Whatta Man.”
