The seminal sci-fi classic spawned a series of increasingly duff sequels and this is the last and worst. The script could've been written by a 14 year old boy; all ham-fisted analogies and running around with guns. Stupid and pointless.
There is some subtext present, but this entry mostly exists to connect the dots of the overarching story and add a slightly different outcome than what we saw in the first 'Apes' movie. Not satisfying, but not disappointing either.
