IMHO, fanservice is stupid. It's thrown in to attract people who are too inattentive, unintelligent, or simply philistine to actually be interested in things like plot, characters, artwork, and storyline to increase sales. . .and it's quite worthless.
For example, I think the 18th episode of Trigun was fanservice to some extent, although of a rather odd variety (fanservice is usually aimed at male viewers rather than female viewers and doesn't usually use characters that have physical imperfections), nevertheless, that was one of the better plot episodes of the series and REALLY didn't need that LOL. The fanservice was really worthless and added little or nothing to it, IMHO: the same objectives could have been accomplished in the story without it.
*MillyFan ducks rotten tomatoes from Ashley and the others who were probably drooling while watching that episode ~.^
