Fair enough, it should be first noted that a series that takes absolute liberties with mocking stereotypes and clichés will go a little overboard; Transformation-scenes go to lengths to display more-than-almost nudity at times, half a lake worth of blood is collectively spilled in only 24 episodes and any object might just explode (Most of them do).
Then again, that's the whole point. More than being a simple parody however, KlK does sport a decent story line complete with plot twists, decent character development (albeit absurd, of course) and a well-matched soundtrack. You'll love KlK, if the absurdist nature is your thing and you're not quickly offended by over-the-top anime clichés.
