We open with war and death, and the fun of shooting a giant gun. And so, in a way, this opening teaser shows exactly what makes Joss Whedon’s writing so great. The humour, believable. real characters, emotion and let’s not forget the explosions, because, they are important you know. But, as well as introducing Mal and Zoe as ex-soldiers, this sequence is all about Mal. We get to see his faith and belief utterly destroyed in a single moment.
