There was too much where they just expected you to turn your brain off and enjoy the story for me too.
It's just boring. Everything happens for convenience of the movie. There are just so many plotholes in this movie its beyond ridiculous. I loved the first movie and enjoyed the 2nd one, but this one is terrible. It's like Xmen Last stand or Matrix Revolution of the trilogy.
How all of these 100's of Apes were captured by that small army while Caesar and his three amigos were gone. No one notices a screaming guard covered in is shit missing. Or that the kids pen is empty the next day after no one on duty last night noticed them crossing the fortress on a wire. Or a small girl can wonder onto a military based unnoticed. Or how Caesar is tucking and rolling away from so many graduates of the Storm Trooper gun range. Or as the apes escape into the hole no one on watch notices how the apes numbers are slowly dwindling throughout the night. Or no one notices the 4 apes following them on horseback along the beach.
There's so many little touches they could have made that would have tied everything together better than what was left on screen.
