‘Sayres1984’ alerted us you can vote for either Batman Begins and Sin City at Yahoo! Movies:
Yahoo! Movies is hosting a Hottest Movie of the Year award, the movie with the most votes will win the award. I think it would be cool to provide a link and urge people to vote for their favorite comic book adaptation of this past year. Batman Begins and Sin City are nominated.
Be sure to put in your vote at the link.
