The whole movie does not care anywhere of plot logic. So if you do not care either and are not watching with your parents (pointlessly embarrassing language and nudity). You might be one of those here, who like the movie. Congratulation! But otherwise, just turn off as soon as you have seen "enough" (this only needs a few minutes).

In particular because the evil side is just a collection of EXPLICIT prejudices about a "primitive old white man" (who more or less behaves like an ape) breaks the whole movie atmosphere. And plot holes on the "good side" do the rest. The whole plot makes no sense, except we assume the main characters are dumb like a fish. Maybe they are! But I hate such plots. This is not forest gump! This is far from being a good move, no matter what "noble spirit" they want to sell here.
