War for the Planet of the Apes

How does a big budget movie get written this badly?

SPOILERS

Firstly, there is no war. There is hardly even a battle... just the start of one. Most of the film is spent seeing Caesar (the smartest ape and possibly smartest living being on this version of Earth) lose his mind and chase a human to avenge the killing of his wife and son. At the risk of all the other apes being killed...???

No, I don't buy it. Totally wrong for the character.

Secondly, despite The Colonel going to all the trouble of launching a special mission to kill Caesar, when Caesar stupidly gets captured by The Colonel what does he do? Does he kill him? No, he doesn't. He keeps him around so that he can cause trouble and ultimately destroy The Colonel.

Dumb.

And the rest is just filler.

I remember really liking the first part of this trilogy. The second part was OK. This final part is rubbish. Which is a complete travesty given the amount of effort that has clearly gone into making the apes lifelike. Great performances there... but you forgot the golden rule -

IF THE STORY IS GARBAGE ... THE MOVIE IS GARBAGE !!!
