Yeah, I see your point about the hefty weapons thing, but after seeing Summer kick SOOOO much ass in Serenity, I can easily picture her as a total badass. And because its TV with a lower budget, I could totally see there being way more hand-to-hand combat, martial arts badassery than in the movies, with more small arms fire, because they probably don't have the budget to be blowing tons of shit up. I mean, size wise she's no Lokinator who you could buy going against one of the Arnoldbots, but I think she'll be great. She can make young weirdos really endearing ... and kind of frightening.
