Most of them, these days.
Chalk it up to seeing that many faceless bad guy flunkies die in the average movie these days. I don't buy the crap that TV and videogames turn kids into psychopath killers (boredom does, ****, I haven't played more than 10 hours in the past six months and I'm leaving computer boxes prominently by the garbage and the lights out hoping someone'll break in and be treated to a warm welcome by Mr. Tramontina), but it'd be silly to say it doesn't have a desensetizing effect when it comes to people you don't know. ****, look at the whole WTC deal- I've talked to people about it, the sort who got all weepy when they heard the news (my own memories of it would serve as another example, but would also ignite a flamewar I don't feel in the mood for yet), and they respond basically in the same way as they would to one of those scenes in every last friggin' movie ever where the violins go all crescendo-ey and the hero shouts something like "WHYYYY??".
Which is all understandable. After all, they're both just images that appear on TV. Next to nobody outside of the New York area actually personally experienced jack ****, and like most major, world-sweeping politics, nobody would have noticed in the least were the news not doing instant replays of Osama's trick tackle over and over and over again while reporters acted all indignant on the noisy box.
