I just find all of the Ape sequels to be unnecessary and kinda bad. Conquest was marginally better than the others. Overall though, I did like plenty of the cinematography in all of them.
And to elaborate further on Libre, if you asked me what to rate it 3/4 of the way through the picture, I would say 3.5/4, but after the final fight, with Eagle Powers™ and all, it jumps way up. The music really helps, too (probably my favorite aspect of the film).
