It was okay. The humans were just as stupid as the plot needed them to be. Why are they still acting like the apes are just animals when they know that they have human or near-human intelligence? Why is everyone on the verge of panic and rioting at the prospect of losing electric power? Humans got along okay without electricity for most of human history. And why is it Gary Oldman’s fault if they can’t get the hydro station working again? They couldn’t find another place to live, someplace warmer, if the apes happen to be living in those woods? The movie is based on a false conflict.
And yeah, it’s San Francisco, not a rain forest. The city would not be completely overgrown with creeping vegetation in ten years.
And let’s bring along the most fearful, stupid, trigger-happy idiot we can find when we go where there might be apes. After ten years the humans would know how much is at stake in dealing with the apes and would be extremely careful in how they proceed. Let’s not bring the guy who’s prone to panic, shall we? If they’d made a point to not even bring guns with them, the initial conflict wouldn’t have happened.
I did like the “not all humans are the same” aspect. When the apes see the conflict between Caesar and Koba, we get “not all apes are the same, either.”
