There is a sinister circular logic to the Planet of the Apes series. Characters journey to the stars and wind up … back on Earth. They travel back in time … and directly cause the events that lead to the rise of their dystopian future. Even as War for the Planet of the Apes concludes the story of the ape leader Caesar, it brings the franchise’s overarching narrative closer and closer to its origins on a desolate, sun-swept beach, one that looks a lot like the one Caesar and his monkey mates gallop across during their quest for revenge. That’s what makes these movies so troubling. It’s not the monkeys with machine guns or the gorillas with grenade launchers; it’s the sense that collapse is inevitable, that even when people (and apes) act with the best of intentions, they can’t escape the cruel hand (or paw) fate has dealt.
