I did, on Friday. I liked it.
There are enough reviews out there and I don't really feel like adding my own two sense. I agree with most of them anyway so I would just be redundant. I thought it was a good movie. It followed the graphic novel very closely, but a lot of what makes the novel so great just didn't translate to the film. Still, it was visually very stunning. I will probably see it a few more times.
For my friends who have also seen it, and read the book and are totally geeking out about it, I am about to blow your mind:
It makes me laugh. It also makes me scratch my head and say "huh?" My theory is that whoever decided to make this cartoon just looked at the pictures in the book and didn't, you know, read it.
My favorite parts:
Rorschach: "I'm nutty!"
"John can give you cancer and then turn into a car"
Remember how the Comedian is Silk Specter's father? That makes this little show even more disturbing.
