I don't normally like episodic manga that makes the characters repeat the same school year over and over, but Ouran is an exception. Maybe it's that I don't expect much from it, but like you say, I like the club as a unit and I'm in no particular hurry for major changes in group dynamics. Oh, sure, I want Haruhi and Tamaki together in the end, and I'm happy to see glimmers of progress in that direction, but I'm not in a hurry.

One thing I have particularly enjoyed has been the evolution of Kaoru and how thoughtful and observant he has become. Like you say, it'd be nice to see some similar attention given to Kyoko and Mori, who I also like. Really, the only char I'm actually meh about is Hunny, because neither his cuteness nor his violence ever amuse me.
