Buffy and Angel fans, look to the stars: The trailer for Joss Whedon’s Serenity breaks online. I never watched the TV show, so I don’t really know what’s going on here, but I could see myself catching this, if for nothing else than for Chiwetel Ejiofor as the villain. Still, that “define interesting” exchange near the end, among others in this clip, just about sets my teeth on edge.
