I'm impressed with the previews. Every frame looks like it was pulled straight off the pages of a comic graphic novel, so as a stylistic exercise alone, I find it fascinating.
The writing was great--very 50's film noirish--which happens to be one of my favorite genres. The Mickey Rourke character was easily my favorite. As for Jessica Alba-she's a bit underused but she doesn't seem to have nearly the screen presence that even Rosario Dawson has. She was great.
