I will always be pissed that they killed Cap, primarily so that Brubaker's wet dream of bringing Bucky back from the dead could be realized. That is the worst piece of retconning tripe ever, in my opinion, because it undid one of the very few permanent character deaths in comics while at the same time delivering yet another fake death. It's crap like that that has made me swear off comics altogether.
How many characters has Marvel "killed" recently that everyone knows will be back? Johnny Storm "died" in FF, now Thor is "dead," Deadpool is going to "die" soon. Most of the Avengers have died at some point. Wanda died and came back from the dead, as did Hawkeye, while the Vision was dismantled. The Wasp has been sent to her temporary reward as well, or so I've heard. Goliath might just stay dead, though there are hints of resurrection around him, too. Who have I missed?
I long ago figured out that the fake deaths happen because either someone has a bug up their a** about some crappy plot twist or because the writers and editors lack the creativity to come up with decent stories any longer. Whoever the hell is in charge of that mess should step back, take a good look at all the fake carnage and swear off pseudo-deaths for the rest of the millennium. If the only thing a writer can think of to do with a character is kill him or her off, it's time to move on to something they can write.
