Just read it. I like the idea of using the sewers as settings for a story, but the execution could have been better. I was hoping for more of a battle of wits between One and the computer guy. And while the crazy guy had a pretty good backstory, overall the story felt kinda empty emotionally. Also, the plot felt... fractured. And somewhat anti-climatic. So, despite interesting settings, not one of the best issues.
It did have its moments. I especially loved it when the gorilla in the underground disco tried to do Avenger in. Just proves how much of a badass Avenger is, he doesn't always need to rely on his extraordinary equipment. Makes me think how much the ordinary Donald's image would change if it was revealed that he's no pushover in a brawl. XD I wish there was ONE story where the ordinary Donald was cool, instead of an unlucky idiot.
