In reaction to Aquaman, the first half, with the actually showing and not telling, was well done, but the bit in the diner was way too on the nose. Likewise, the first page with absorbing man felt really forced.
Titania's page was better done, though she seemed to misunderstand the situation as "Odinson is now a woman" rather than "The mantle has been taken up by this new woman."
But in short, the parts where the comic dialogue started meta-responding to the real world directly didn't work in Aquaman's book either, and I like Aquaman a lot of the time.
As a counterpoint to how to do this very well, when Rhodey switched actors, there was a huge furor about it, and they put a "Deal with it" into the movie, but in the context of the movie it was something else entirely. If the meta-criticism was worked more naturally into something else, it would be just as pointed, and probably more effective.
I don't think either case is wrong for wanting to address detractors, but I don't think either case did it well by having the text and the meta-text be the same.
