Yeah, I have to say the coloring on a lot of these books were VERY good, especially since colorists rarely if ever get the credit they deserve.
I think there’s definitely a component of that, but I think what makes the Black Lanterns work so well is that they take what’s scary about zombies and take it to the next level.
I’m reminded of something that Simon Pegg wrote for an intro for The Walking Dead first volume paperback. There, he talks about how while the shambling, the rotting flesh, the tearing of people’s entrails, that’s all bloody gloss over what makes zombies truly terrifying: death. The slow, approaching, inevitable death of everyone you know and…you. The idea of seeing someone you know and love, suddenly being back, a seeming miracle, that ultimately becomes a nightmare.
The Black Lanterns take this and crank the dial up to 15, let alone 11. Because they speak – not only do they speak, they speak all the most terrifying, personal things that you are afraid of, because you’re afraid that they could be true.
So yeah, all that rambling to say that I really like that “getting a rise” out of stuff the Black Lanterns do as well. 
I’m still not entirely sure how fully in character that was for Kori. Like, she’s a very blunt woman, but she is also very much in touch with her sense of love. I think she would absolutely hate Tara for what she did, but she would also understand Gar’s love for her, even if it’s for a an idealized version of a girl that simply never existed.
Absolutely. I think her arc in this event is going to be a fun one to reread again, because I think it’s fair to say that the Mera that we know and love today really started here in Blackest Night.
