Just so you know the quote is from the episode Serenity, which is the pilot for Firefly. The movie which takes place after the series has the same name.
You should totally watch it. We're doing a first time watch right now, only on the second ep, you should join us!
I tried watching the TV series. Didn't get into it at all. I wasn't rooting for the right people, apparently....let's just say that if I lived in the FF-verse I would be more likely to be a "purple belly" than a "brown coat".
So I am definitely not the target demographic for a show like this!
