re: Dawn of the Planet of the Apes (Thoughts with Spoilers; Fricking fantastic)

The fear is many if not all of the apes were held captive by humans

Humans show up and shoot ash

Speaking apes make a show of force...humans are now scared too add to the fact some blame the apes for the virus

Humans have a shite ton of guns...apes have none

That makes for a tensious situation. Caesar would have let them use the plant regardless but I do think it was odd no one protested on the grounds of strengthening the humans position thereby weakening the apes, and it meant increasing and perpetual ape/human interaction. I guess the other relationship factors were more than enough to cause a war and justify ape mistrust of humans being around

I'm not comparing the wrong thing...
Had Caesar said no or even hesitated, there would have been a war instantly. All of the other situational aspects would have been rendered meaningless in terms of stirring up mistrust and paranoia. It would also make everything pretty black and white. Of course the humans would go to war, could you blame them? They need power. It would have made the story less compelling and complex instead of more. Koba would not have any grounds to usurp Caesar, and him being the villain (not Dreyfus) was one of the more surprising and refreshing aspects of the movie. I don't want a statement on human violence and reliance upon technology

I found it to all be logically consistent.

Additionally the conversation between Caesar and maurice in the beginning gives a great insight into caesar's decision making in terms of the humans. To HIM, they kill each other and any concession he grants them won't change what is inevitable in his mind. He views humans as SELF destructive and that view is bolstered in the only rule of their society...ape no kill ape.
