Overall, I loved it. There's a bit of a lull heading toward the mid-point where Korine's use of repetition feels really, well, repetitious (at other points this works to nice effect), but then Franco and the girls bust out a Brittany Spears ballad that will without a doubt be one of my favorite scenes for the entire year.
The camera work is phenomenal, the cast is great, the music is epic. It's anarchic, gratuitous, and a hilarious satire. An ode to the American dream and the most fearsome creatures on the planet: teenage girls.
