Personally, I would have put Xena at the top. Barbarella, Wonder Woman and Storm, as well, would have been higher. For quality of the work, Alien was far above all the rest, though. Sigourney Weaver was incredible in in that whole series.
I feel like I’m intruding on Brain Rage’s territory here. Or worse yet, doing Rule 5 blogging. What can I say, I love campy science fiction.
