That is a good point. I've seen little of the tv show, but have watched the 1st 2 movies several times. I guess the biggest difference is that Sarah (movie version). for the most part, doesn't rely on sex appeal as a weapon. In retrospect, I tend to be drawn more to characters like her (e.g. Ripley from the Alien series, season 1/2 Kara Thrace from BSG, Aeryn Sun from Farscape and many book/comic characters).
