Deaths in comics is never easy, especially if its a character that we love and cherish. I remember when Ted Kord was killed. It got me so upset that I swore off of comics for a while. And Jamie Reyes; gotta say, it didnt help that some little upstart peckerhead replaced one of my favorite characters.
Some comebacks should be expected though. Superman, Batman, Captain America, Wonder Woman, Green Lantern- these are characters that you cannot expect to stay dead. Why? Someone else mentioned the magic word: revenue.
Yeah, some deaths are cheapened by time travel, magic, etc. But guess what? We all bought into it. Keep in mind that the big two are companies. While we would love for them to keep bringing out awesome character and spectacular story lines, their main goals is to make money. And they know that a death or a rebirth will generate revenue.
The movie sucked. So, no, lets not try a show again. What I would like to see is simply another Gen-X titled comic. They could bring back whoever is still alive from the original team and throw in some new mutants. (on a personal note- i miss Banshee)
