To me, this smacks of too much wink and nod. It's supposed to be bad, but not too bad that it ticks off the sponsor, but at the same time trying to recapture what made promotional comics in the old days awful in their sincerity. And from what I read in the preview..ehhh... they don't capture it well. I can buy that Sanders here is the immortal mascot and the whole backstory of a guy just trying to sell pressure cookers but being successful in selling a recipe intended to market the cookers instead is thrown out the window. And, yes, the whole concept of an evil, alternate Sanders that sells terrible chicken (again, throwing out any realistic context about the real person for the sake of mascot), kinda seems funny enough for a tongue in cheek sort of Super Hero cliche riff.
But they use the serious versions of the characters, not some retro Silver Age parody version. That's... that's something that doesn't work right.
