Below I gave my opinion of a film that is based upon a classic zombie novel. But, zombies are not the only post-apocalyptic creatures in film lore. Other than the walking dead there are the talking apes of the The Planet Of The Apes franchise.
And I find the zombies of the 28 Days Later mode silly. The dumb, slow zombies of The Last Man On Earth and Night Of The Living Dead to be more scary, simply because they at least obey semi-plausible scientific realities.
So, forgetting whether you like zombie or ape flicks more, you have a choice. The world has ended. You are alone in the world, until you discover you are not. Which would be a scarier menace to face? The walking dead who will try to eat and/or infect you to become one of them? Or the apes, who are scared fascistic, enslaving, religious lunatics? Bear in mind, as long as you were healthy, you could likely avoid the zombie hordes, and dispatch them with ease. You would be the smartest creature on the planet, possibly a 'legend.' On the other hand, in the ape world, if they knew you could speak, they would hunt you down, lobotomize or kill you, and, even if mute, they would enslave you? You would be the low man on the totem pole, rather than at the top in the zombie world.
Here are snippets of the sorts of zombie hordes you would face:
And here is what you would face in the ape world:
Gotta love the fascistic gorilla played by James Gregory, who also boasts, 'The only good human is a dead human!'

Ok, times up....which scenario would you choose, and why? Personally, give me the zombies, because I would have a more realistic shot at survival. After all, on ape world the humans are all deaf mutes or psychotic mutants, whereas there would have to be survivors on zombie world, and connecting up with them would allow a new world to begin after the cleanup of the dead, which might take a lifetime. But, how would one insurrect ape world with a bunch of mutes and mutants?
