Yeah, I'm still in the early chapters of the first book, and it's a slow slog just because I am having trouble with the writing. But so far, I share your feelings on the captain of the guard dude. Stocism is only interesting when there's a hint of deeper passions and feelings underneath. So far, he's all cardboard.
Then again, the main character hasn't been entirely interesting either. I'm getting a lot of tell and not enough show.
