I liked the movie, mostly for the fact that it took itself seriously, telling the story smartly, with a few nods to its predecessors (Caesar, the ape, builds a 3D model of the Statue of Liberty, and later, one of his captors watches Heston's version on TV), but without their unavoidable hokeyness.
Many of the sci-fi/fantasy films and TV shows from the '50s and '60s seem campy to modern viewers. It's interesting to ponder how much reactions may have changed over the years. To be sure, a monster pic like "Them!
Was it possible to make a monster film in the '50s or '60s without making it campy? The technologies, effects and techniques of the time certainly didn't lend themselves to much seriousness. The apes opposite Heston were clearly people in monkey-suits (and Heston, well, he was Heston.) A decade later, George Lucas showed the world how to take those costumes seriously, by treating them as matter-of-fact, with the frankness of a contemporary documentary (see the "Cantina" scene in "Star Wars
This new "Apes", at once a re-boot for the series, and a re-make of "Conquest of the Planet of the Apes" (1972), exemplifies how far the degenerate genre has come in the past forty odd years. And as the genre matures, so do its stories, becoming more nuanced, more character-driven.
Of course, this doesn't mean that new adaptations of old, campy films always turn out well: See Peter Jackson's "King Kong
