While I'm not generally a fan of the overuse of shadows, the art style in the book is fitting. Although the dialogue displays a certain level of confidence, it is clear from the facial expressions and use of shadows that there is also a hint of shame mixed in there, as well.
One thing that I am worried about however, is that this story may develop into something bigger than it already is. The series runs the risk of going over peoples' heads as the heaviness of the plot mounts. It's a line that Hickman has walked perfectly so far, but there's a chance that he might cross is in some future issues.
I will admit that the talking and moral acrobatics can get a little tiring, and I'm glad that New Avengers #4 ends on a note that will no doubt bring some fighting action in the next book. After all, while the mind is certainly a powerful weapon, it's oftentimes not as satisfying as a good spell, claw strike, or repulsor blast.
