I saw it Saturday. The opening scene is very Hollywood/contrived - ridiculously over-the-top. So I figured the movie would be this way throughout. But the close you got to the apes, the more the story and characters evolved, the more you felt like the apes were real. And when the apes raid the armory - the guns are pretty cool too. Lots of SCARs, ARs, M249s, and maybe a few of the new Berettas.
It gets 8.5 on IMDB and I think this is pretty accurate.
It's pretty damn good I think.
