Serenity

12) Shepherd Book. I almost mentioned Wash here, since his death in Serenity upset me tremendously — but at least Wash’s death made sense in context. Wash gets to die heroically, piloting the ship through a crazy dogfight over a scary planet, then gliding a dead ship to a landing (almost) everyone can walk away from. His death is jarring and shocking, and it feels like we get to love him all over again before saying goodbye.

But Shepherd Book on the other hand — he feels like a throwaway character in the movie, and his death is pretty pointless. He’s just there to mouth a few words about spirituality and then get wasted. And his death, unlike Wash, is purely there for plot-hammer purposes. He’s Uncle Owen and Aunt Beru — he dies so that Mal can realize that there’s no way to hide from the Operative any longer, and he’s too mad to keep hiding. It’s the plot-device death that lets Mal turn to the camera and (pretty much) say "Now it’s personal." He’s Mal’s girlfriend in a refrigerator. Shepherd Book deserved so, so much more than that.
