Despite enjoying this issue, I'm a bit torn on it. And not for the reasons most of the Superman fandom seem to have mixed feelings right now. I'm fine with Clark not having a secret identity and being depowered because I know this is temporary, no matter what DC Editorial says. Like the electric blue and red Supermen of the 90s, this too shall pass. And the idea is a fun one to play with for a time.
No, my issue is with the idea of Mythbrawl. It's a great idea, mixing the shtick of JSA villain Roulette with the idea (best explored by Neil Gaiman in The Sandman) that old gods take on new jobs in modern society to draw what worship they can. Yet as innovative as Gene Luen Yang was with this concept, I can't help but think this sort of thing is more appropriate to Wonder Woman. It's a minor quibble, however, and this issue is well-written.
It's been a while since I've read a book with artwork by Howard Porter and I honestly didn't recognize his work here until I looked at the credit's page. Porter's style has changed since the days when he was on JLA with Grant Morrison, becoming stronger and less stylized. The vibrant colors by Hi-Fi perfectly enhance Porter's pencils and inks, crafting one amazing looking book.
