Rapture ideology, I believe, is a product of anxiety about death. It’s a way of coping with the fear of death by denying its inevitability, inventing a way that some special few of us will get to escape it.

"Rise of the Planet of the Apes" ended with the spread of a virus that kills humans while making apes smarter. Remarkably, this felt less like an apocalypse than a fresh start. Humans in that film, with the possible exception of James Franco, are portrayed as sadistic, slippery, and selfish, while apes are compassionate, candid, and cooperative. Humans manipulate nature for their own ends, while apes live in harmony with it. I can’t think of any other film where you feel like cheering when another species takes over the world. By comparison with the famous conclusion of the original "Planet of the Apes," with Charlton Heston venting his anger at the remains of the Statue of Liberty, the ending of "Rise" is not so much “Damn you!” as “Damn, you!” as the audience cheers on our successors to the top of the food chain.
"Dawn of the Planet of the Apes" does its predecessor one better by asking us actually to think through the moral and philosophical implications of a post-human world. Rise offers an escape valve for human excesses that evades broader questions of culpability, while Dawn suggests that our limitations as a species are not so easily evaded. The central moral revelation of "Dawn" comes when Caesar realizes that his former belief that apes were better than humans was false, and that the similarities between the species are as important as the differences. This revelation is actually a much deeper one than the hackneyed “Can’t we all just get along” premise, since "Dawn" is honest enough to recognize that mutual understanding will inevitably exist alongside mutual loathing.— “Apes vs. Zombies: New Skin for the Old Apocalypse in Dawn of the Planet of the Apes" by Jed Mayer (IndieWire).
