Mia Kirshner and Scarlett Johanson were good. Hilary Swank and Josh Hartnett, meh.
This movie has a resolution, but it was one out of left field, with really no clear motive. So it was a stretch. I liked this one more than Hollywoodland, because they tried to resolve it, but this too, I am completely alone in my opinion, most people hated it.
