I can go either way on Krypton's destruction. For me it boils down to execution and (more importantly for the long-term) what it adds to the mythos.
I like the "cautionary tale about environmentalism and arrogance" angle that MoS went with. Its a strong, non-intrusive moral that is always in fashion to one degree or another. But I like what the cartoon did with Brainiac too, who wasn't responsible for the planet's destruction but was for the species becoming extinct. That made it so much more personal. It paid out dividends over time and enriched the narrative.
I think Bendis does possess the talent to do this right. But it'll depend on which "Bendis" shows up.
That Reis art is everything. Is it me, or he just getting better with time? I wish we had gotten him to draw the Reborn costume more. I have become a very big fan of Clark's almost-previous costume. They finally got the belt right, and now the trunks look weird to me.
