Fair enough, and I agree they should create more new villains that expand that representation. I was also disappointed to see her go that fast.
I guess the thing that surprised me about your reaction was the severity of it. I saw her early death and went "oh, that's too bad" and moved on--but from what you've said it sounds like your reaction was more like "this sucks; I no longer have any interest in reading this miniseries at all". Of course, you've always had a special fondness for snake-themed villains, so it hit you in a sensitive spot.
