These two issues take to the Possibility Zone, the creative myth making of America (the central theme of this comic so far). In what seems to be an unironic take on the issue the Zone is dead filled not with creators but the leftover creations of the disappeared creators.
Of course it's a bit too much to ask what it would be like to be a creation abandoned for 300 years. This isn't Frankenstein you know. What happens is that you go mad, murderously mad and the expedition crew naturally have to fight and kill them. Just as they've done in all the other Zones. Because at it's heart everything in America is driven by violence.
In this story arc we're seeing Argentinian journalist Val's backstory, born to wealth and power and with a life overthrown by war and revolt. It's slightly more interesting than some of the others, less so than Ace's. There's some meta humour about comics and superheroes. It's all okay.
The gang has to create the Great American Novel to escape the Zone and move on. Since you know that there's not really a story unless they succeed and you know that ultimately they have to reach the end of the quest there's not a great deal of narrative tension. The most that is at stake is whether any character you care about is going to make it. The problem there for me is that I'm not particular invested in any of the characters or the overall jeopardy of a cure for the world plague.
I'm on the verge of cancelling but let's see how this arc plays out.
