... with a pretty strong exception. The Song of Ice and Fire author has always been a Marvel nerd, and recently told MTV Geek that he would love to write Doctor Strange comics -- but it can't be rebooted or retconned.
I would have to have my lawyers to meet with Marvel's lawyers and work out an absolutely iron-clad contract that would say whatever I did in the story would continue to be canon forever, and would never be retconned, rebooted or reimagined out of the universe when some later writer decided to mess around with it. Because I hate that, I hate — I've always hated reboots and retcons and the fact that a writer comes in and undoes what a previous writer did and, y'know, brings dead characters back to life, kills new characters that weren't intended to die. That's the one thing I don't like about comics. That drives me crazy.
So what do you think? Is it worth it?
