Hmm, most of my last post mysteriously vanished…strange. I was basically reiterating my point that Maison Ikkoku plays it very straight, whereas Love Hina goes for slapstick and Chobits features sci-fi elements. Also, both shows owe a heavy debt to MI in my opinion - there’s a scene in the Chobits manga of Chitose sweeping outside Hideki’s apartment that is almost certainly a nod to Maison Ikkoku.
Fanservice. Okay, MI has Akemi but she doesn’t feature that often. As for references to Kyoko’s panties, nothing sticks out in my mind (although I’ve only seen around a third of the show). And anyway, do references count as fanservice? During the show there are numerous sexual references (in one episode Godai has stacks of porn mags strewn across his floor that he hastily collects when Kyoko comes a-knocking), but this reflects real life as a drama should. By todays standards, MI does not have much fanservice. It certainly doesn’t detract from the plot, anyway.
