Oooh! I thought of one the other day. I don't like it when a book's first chapter lavishly sets up a character, makes me interested in their backstory, gives me someone to root for in the novel, and then BAM! at the end of the chapter, the character dies to prove that the WEREWOLF / METEOR / GLOBAL WARMING / WHATEVER that the book is *actually* about is, in fact, dangerous. I hate that.
