Do you love The Empire Strikes Back? If so, it's time to show your support for the film by voting in a movie poll.

The bracket has reached the final round, and only Irvin Kershner's Empire and Joss Whedon's Serenity remain. As Star Wars fans, I believe our duty is clear. Click through to io9 and vote now!
