Watched it today and thought it was awesome! I had to remind myself occasionally that the apes were all computer-generated. The special effects meshed in with the story so well and the story was strong enough that I sometimes forgot I was watching special effects.
I couldn't find any major logical flaws in the plot, they seemed to cover all of their bases pretty well and you can already see the groundwork being laid for the apes to take over the entire planet. Hope to see a sequel soon; but then I've always been a sucker for stories where animals rise up against humans.
