The King of Fighters
perhaps the reaction has more to do with ppls amazement that disney/marvel had the balls to finally kill someone. We've been faked out many times from Loki, to fury to Thor and so on. Had nothing to do with liking quicksilver, what was there to like? Other than that scene where he and his sis explain their motives/his catchphrase we just got stares
Well, when they turned good, he did display acts of heroism, saving all the people from the train (you could say it was under Cap's "orders", but still) and his death in itself was an act of heroism as well. He also was never really shown to being evil anyways and while I do feel that both him and his sister could've had even more development (but hell, movie had so many characters, plots and things going on and obviously so much was cut too, I can see the difficulty in balancing, but think what was shown even was mostly fairly well done) what time they did have on screen, did show a moderate personality from the both of them (I think even more from QS than BW actually) and you could see their motivations from their tragic upbringing. Also, Quicksilver was shown to display great care and concern for his sister (naturally), so I can see how some folks liked him. My 14 year old niece said he was her favorite character in the movie and was sad that he died so soon in the series.
