Honestly, I would. I'm of the school that characters should die, but only in cases were it is called for. Even if they all eventually come back. If you listen closely you can hear the pitter patter of Barry Allen or the swosh of Conner Keny on the wind . I am not about characters being killed off just because a writer doesn't know what to do with them or they don't have a place in the universe anymore. I've seen too many great characters revitalized to ever write someone off entirely. Hell, Speedball was a joke six months ago, now look at him.
More to your question though, I'm very anti iconic characters getting offed. In my eyes I view Black Panther as every bit important as most popular marvel characters to that universe. Now, he might not be as popular as the popular characters, but still important in the workings of the MU. Very much like Black Bolt is. If Black Bolt were killed, I would care, even though I don't really follow his story. These types of characters have such rich histories and importance that I like to know they're around. I even cared about the "death" of Donna Troy and I wasn't reading (or read in the past) Titans. This could be just because I'm a big softy, but I do take notice when "big" or "semi big" characters are offed, especially when they have lengthy histories.
I guess I was confused because I thought I remember you saying you've read, and liked, the Black Panther run done by Chris Priest. So I was a little taken aback by how quick you wrote the character off. It takes a lot more than a bad issue, or bad run of comics, for me to stop caring about characters. If you just jumped on BP for Civil War purposes, then I see your point better.
That is exactly what you should do. Vote with your wallet and stick to your guns. I won't argue that the "Storm is black, Panther is black...so lets marry them!" may have been lazy, but I really do wish it works out. It didn't develop naturally, like say Kitty and Colossus, but in the hands of a good writer I think they can be nearly every bit the power couple that Reed and Sue are. Of course, the X-Office will come calling back for their girl in a year or two, so fat chance of that happening, right?
It's a little hard to think you aren't upset with the characters (even a little) when you say "Yeah, he and Storm are gonna get a divorce, and they're both gonna die terrible, horrible deaths by the end of the year. I don't care!". But if you say you aren't I won't argue with you.
Happy to be here.
BTW - I dig how the quoting system works on this board. It's quite nifty.
