Planet of the Apes
Saw it this morning.
I will say this... it didn't FEEL like I was cheering the end of the human species.
Contrary to what PETA said (IIRC) the apes weren't getting their own back, not getting some sort of revenge against humans. What the movie does is establish how the apes got smart and set up the reason they were able to fill a void. The movie used an amazingly light touch in dealing with animal research. None of the villains were among the scientists or researchers. That medical research was dealt with as a complex thing and the motivations of the researchers shown to be anything but evil, made the simplistic treatment of the three individual humans who were villains a disappointment. Important plot points depended on teh stupid. It would not have been hard to do better.
