Like hell Supergirl's death wasn't particularly interesting. I based my whole fanfic career on refuting that.
Heh. While I'll grant you that there's story potential to be mined in the idea, Wolfman didn't do it, and the most interesting thing about the entire incident was the Perez cover.
I mean, they (heroes who don't kill, by the way) had to kill the Anti-Monitor, what, six times? And two of them take The Ultimate Sacrifice(TM) along the way? Doesn't work for me. In the hands of a writer with a better understanding of escalation and emotion, maybe, but Wolfman hasn't ever really had much range beyond depression and angst.
Crisis was a fun ride at the time, but I don't think it's aged particularly well, and the drama just doesn't work. But it'd make a great springboard into real stories, which sounds like what you've done.
(I wouldn't know--I've used your reference materials time and time again over the years, and your writing has been recommended to me on numerous occasions by very bright people, but I've just never gotten around to it.)
