I don't know... Falcon and War Machine are pretty fun. I liked Quicksilver, but we didn't get enough of him to get a sense of his personality or character. Too bad that might not come later in the MCU. I also like the idea of having the twins as a packaged set of characters, so it's too bad that is no longer the case. But I guess at least Wanda won't have to share her development.
Not in the movie, no, we didn´t see too much of his personality. But he is an old character that already has a lot personality... I mean 50 or so years of comic and cartoon history is quite a lot. If I didn´t know the character before the movie I might feel more indifferent about his movie-death, but as it is... Quicksilver is my fave character and I was SO happy to see him on big screen in a version that promised to be more "true to his character".
And as for Wanda... without her twin she just is not complete for me and also less interessting.
I really loved depiction of his super-speed as well, that bluish soft trail in the air, etc. AoU has made me Marvel fan, and then they stabbed my heart with his death, that was somewhat unnecessary, imo.
