Okay, this review is going to be nothing but ***SPOILERS*** but it's been out so long, I'm sure no one will find it devastating... But let's just start with the first sequence, as James Franco is talking to a board of investors about a medicine which he tested on a chimp called Bright Eyes (homage fail) that VERY chimp they're about to showcase runs amok and, though we find out it was protecting it's young, doesn't stay and PROTECT IT'S YOUNG, no it goes on a rampage ENDING IN THE VERY ROOM WHERE SHE IS BEING DISCUSSED. Now, if at that moment the ape laid dying on the table said "Ladies and Gentlemen, I here's Bright Eyes!" I would have settled in... But no, I knew I was in for an ugly ride. Let's talk Alzheimers and the drug that sets all of this in motion. Frano takes the drug (and the baby chimp) home to try and make his father better. Actually he took the chimp home first, and after 3 years the chimp is doing well, but Lithgow (the father) is a mess... So Franco tries the medicine and lo and behold it works! In fact, like in the chimps it improves Lithgow's mental capacity...
Then another 5 years pass, during which it seems Franco has held an honorary position at the pharmaceutical company since he seems to have no other project but the secret Alzheimer's medicine, and, sadly, the effect of the medicine wears off. At this point, Franco tells his boss about the medicine, but says it's incomplete because it stops working AFTER FIVE YEARS!!!! Do you know how many THOUSANDS AND THOUSANDS of dollars people would pay to add five QUALITY years of life onto a family member with Alzheimers. But, for some reason the ambitious money hungry boss misses this, but allows Franco to pick up where he left off.
Then John Lithgow dies. Obviously the medicine is a failure if it killed a 70 year old man, right... I mean that's cutting a few years off the actor's age at the beginning of the movie. Remember EIGHT YEARS PASS. So, I dunno, Alzheimers and monkey medicine aside... Maybe he just died because he reached his life expectancy?
Now, okay, I'm not even going to get into Draco Malfoy and why someone who hates chimps would dedicate their life to working with them... And I guess this is explained away by him being the owner's son, but still, Brian Cox didn't seem to care that much for them either.... ANYHOW. At the end, okay, I know the helicoptor is shooting at the apes, and it's now crashed on the edge of the bridge, and there's Bright Eyes, looking at Jacobs, the money hungry drugs maker, seeming to say "So you're the secondary antagonist I've never met. What should I do with you." So he calls over a second smart old ape who DOES know Jacobs and he seems to say "You're that jerk that gave me SUPER INTELLIGENCE!!!" and proceeds to kill him.
All this being said, a Chimp yells NO! and rides a horse. So on THAT level, it works as a fun summer movie and once I decided to let go, I kind of enjoyed it.
