Film characters tend to be an unstable lot. They're prone to flying off the handle at the first opportunity, either for the sake of comedy or for sheer unadulterated violence. Of course, when they've been traumatised beyond all reasonable expectation, you might allow them this catharsis. After all, characters like The Bride in Kill Bill fully deserve to dole out murder-fests she lost her in-laws, was put into a coma and seemingly lost her child all in one fell swoop. If anyone's allowed to cut up Japan, the USA and South America, it's surely her. Yet for the sake of this list, I'm not too interested in her, or other characters who indulge in righteous fury. I'm more interested in those characters who dole out retribution completely at odds with how they've been slighted. If they were given the wrong meal, they'd burn down the restaurant, if their car was lightly shunted, they'd blow up the car park and if they were punched, they'd destroy the punching party and their entire family. It's disproportionate is what I'm saying, and though we all appreciate the plot being moved on by people reacting to events, you've got to say this lot take the biscuit. What they really need is to be sat in a dark room and calmed down, so they stop doing silly things like this. Obviously, a SPOILER WARNING is in effect. If you don't want certain well-known (and often excellent) films ruined for you, stop looking now.
