I don't see that there's necessarily a contradiction. For years, my favorite DC character was Barry Allen, but I recognized that his death, and his staying dead, was invaluable. Bringing him back didn't cause celebration from me.
Okay, I get it. And I'm still not thrilled with Barry being back. I really can't stand the way Johns writes him in JL at all. It's like half the time he sounds like Barry and the other half he's sounding like Wally. MAKE UP YOUR MIND JOHNS!
But Jean has been considered a character of rebirth since the 1980's. There IS a reason for her to come back. Her first "death" was needed and made a huge impact. Had she stayed dead I would be in the camp of "keep her dead" as well, but since she's already come back once... then let's keep the tradition alive!
