Eh, I have a bookshelf full of eroge, and I don't feel like KLK is aimed at me at all, haha.
Obviously it's somewhat dependent on personal taste, but KLK comes off as joke mockery of sexiness rather than sincerely trying to please me. Contrast with other shows that actually are genuinely trying to service me, like Infinite Stratos, Freezing, YuuShibu, Wanna be the Strongest, or Machine Doll.
KLK's character designs don't make much use of modern bishoujo sexy-cute conventions, and Satsuki is so far away from that that people call her "man face."
KLK also spends too much time showing the characters' faces in "non-pretty" ways, like deformed gag faces or exaggerated shocked faces or a face made up of tennis-ball bruises. You won't see much if any of that in the shows I listed above because the girls are supposed to be pretty at all times in those (even when they're injured, or in some cases, especially when they're injured...).
I wouldn't even be watching KLK if my friend wasn't so excited about it, and he has generally the opposite taste from me. He ran out of the room when I started watching Wanna be the Strongest in the World, lol.
Of course, the above topic is a separate matter from simply finding all the T&A distasteful, independent of who it or might not be pleasing.
