It's interesting, because the actual physical detail (characters, surroundings, buildings, etc) are so bare that your mind's eye only visualizes the players most of the time. Kind of like one of those plays with no props, set pieces or character costumes. In a weird way, this let's you focus on just the personalities, without spending too much time thinking about the environment.
I appreciate this author's ability to add humor into most situations. Things go from harried to lethal, and yet throughout it all our author keeps the tone light, mostly through (verbal) quips and jabs, and to a lesser degree by the characters sort of having a fatalistic-but-we-are-never-going-to-give-up type ethos.
