In anticipation of this year's San Diego Comic Con, SciFi Squad and Horror Squad have launched the ultimate fan polls, asking you readers to vote not only for the best films of all time in their respective genre, but also on favorite characters, female heroines, films from the past year and so on. We're going to ask you to make some tough choices here, but that's the point -- how else are we to determine the best of the best? So check out our Ultimate Sci-Fi Fan Poll below and vote away! When you're done, head on over to Horror Squad and do the same. We'll announce the winners just in time for this year's Comic Con.
