Too bad they never made a sequel
I'm not saying that this was a great movie, or that the ending made perfect sense. But the ending was interesting and intriguing, proven by the fact that people still argue over it.
And a sequel to it would have given us something not seen in 8 apes movies so far, the apes in control of a mordern day society. Regardless of the first movie, that would have been cool to see.
