If you are one of the few people who missed the 2011 James Franco vehicle The Rise of the Planet of the Apes, the more successful of the 21st century Planet of the Apes franchise reboots (the other being the humiliating 2001 Tim Burton Planet of the Apes remake with Mark Wahlberg), the first couple of minutes of Dawn of the Planet of the Apes , directed by Matt Reeves (Let Me In, Cloverfield), does a decent job of filling in the blanks. Those blanks include a simian virus that decimated much of the human population, unleashed by a greedy pharma corp anxious for profits from a potential treatment for Alzheimer's.
Through the wonders of CGI and various computer generated apps, the apes, led by talking chimp Caesar (Andy Serkis) and his close associate, the aggressive Koba (Toby Kebbel), exist relatively peacefully, hunting other wildlife for nourishment, in the woods. But the arrival of a group of humans, including Malcolm (Jason Clarke), Ellie (Keri Russell) and Malcolm's son Alexander (Kodi Smit-McPhee), desperate to reactivate a shutdown dam near the forest to restore their diminishing power supply in what remains of San Francisco, threatens the balance.
Full of the kinds of messages one would expect in our current (human) political climate about how fear makes others follows (a page ripped from the Republican playbook) and the intrinsic value of trust, Dawn of the Planet of the Apes, gives the audience a lot to think about while watching the outstanding special effects and action sequences. Finally, a true summer blockbuster has dawned.
