Basically this was a rewrite of "King Kong." Ape gets imported from Africa and becomes too powerful for its handlers, and there is a shoot out involving high places at the end.

A lot of the special-effects ape movements were just about as realistic as those in the original "King Kong."

So what is the message of the movie? Feeling any anger? Suffered any abuse? Then the highest degree of violence, mayhem, and murder should do it for you. Bah!

In the original planet of the apes the implication was that humans devolved (inability to speak, for example) after suffering a major self-inflicted downfall. This movie implied that all humans would perish. Where we do see significant devolution in this movie is how low have become writing standards today compared with, say, 1933. I am sure there are chimps that could produce a better screenplay. And I wish they could have been chosen as screenwriters for what turned out to be this simpleminded simian slop.
