That last one reminded me of one of my favourite scenes in Van helsing. One of the vampire brides is about to kill Anna Valerious and goes into a long soliloquy about how she's going to enjoy killing her. Anna manages to signal to the friar to throw her a stake and promptly stabs her in the chest, saying, "If you're going to kill someone, do it; don't just stand around talking about it." A nice way of subverting cliche.
