I'm sure Oberon would love the show =P.
I understand your point, though I view it as a different kind of silliness. KLK is certainly stupid and silly, but the constant fanservice did not actually add to that. It just provided a different kind of content outside of its main focus (which is being crazy and having cool fights). I do not mind the characters being clothed the way they are so much due to the point the show makes, but the zoom-ins add nothing to it. It certainly hurts the show way less than it would hurt a more serious episode, but I would personally still say that the fanservice slightly harms the show simply by being completely unnecessary and existing.
It is certainly not intended to be taken seriously. My only point is that the fanservice in that show is a waste of time.
To be fair, a lot of things in Kill La Kill is a waste of time, we tend to use waste of time as a negative. I don't think it was needed, on the flip I don't think it hurts the series in anyway.
Though I guess it's really a matter of opinion.
