Love the movie, an evolution of Apes into something great.
However one matter that aweful regrettably was, Raka shouldn't save the girl.
After Caesar died, Raka the only last valuables link.
If to create conflict amongst the Apes, then need to keep Raka alive.
So he may relive and keep legacy of Caesar.
The girl not worth it, just another weak story link.
Please focus on an evolution of Apes instead on human so may create very different angle of view.
Too much story of human would kill the story completely.
