I'm a librarian who loves anime, manga, and reading a wide variety of genres.
I usually try to wait and post at longer intervals than this, but I couldn't help myself. I think Wheaton is the only male narrator I've listened to in recent memory that makes zero effort to change his voice to differentiate between male and female characters. Robin Baker sounds exactly like everybody else.
Wheaton's narration leaves me feeling torn. On the one hand, like I said, he's got an easy-to-listen-to voice. On the other hand, he seems to have a range of maybe three or four different kinds of voices (blander and gentler voice, craggy voice, government guy voice, and normal voice), and the cast definitely includes more than three characters.
