Well, I don’t see that the narrator deserves comeuppance for having such a harsh worldview, but if that has no bearing on the story I can see how it’s obnoxious. I don’t know why Wil Wheaton happening to be the audiobook reader has any effect on it being a problem. If it is relevant to the story it could provide a window into a jaded and hopeless mind. I’ve never read it, I don’t know, so I can’t say that it kills the mood since I have no idea how out of place it is.
I meant that he doesn’t get comeuppance for being an insufferable asshole through the entire book.
And I imagine Wheaton was reading it in the sly voice he does that makes even the most innocent things insufferable.
