KnK has such a loathsome script that I could not tolerate it at all, except for that one idol episode which had no attachment to the larger plot or to most of the really awful comedic threads that they repeatedly reused. It's really, really bad.
People generally don't talk about it because most of us want to forget it existed.
KnK was a show I would watch late at night while falling asleep and all I can remember is that all of the characters were dumb and/or annoying, the plot made no sense and nothing ever really happened. And something about glasses.
But the art and music was nice so it was good to watch while falling asleep, and I liked the OP.
