"Kingdom of the Planet of the Apes" could very well leave you asking this question (and of course you are perfectly entitled to): Where are all the humans? The answer to that also provides one of the most diverting aspects of the entire film. The humans are preoccupied with a vault containing all that is needed to get the satellite communications started again. Could this possibly be a tantalising precursor to perhaps yet another film? But if so, where would another film lead? It can only lead in a circle with the apes and the humans battling it out over who will have dominance over the entire planet. Anyway, this current installment is slow moving for the most part, although it is also wonderfully entertaining and the visual effects are a tremendous triumph as with all the other preceding films.
