Y'know, in the end I'd have to say I liked the first better than the second. And that's despite the fact that I actually really liked the crossdressing character, and actually as characters liked most of the new ones fine. But it got too . . . artificial. The first was a manga about otaku being people; they were being ot-aku=culture-y, but just as people who were in that culture. The story itself and the ways people interacted was pretty naturalistic. It was a pretty dashed good slice of life that had a real feel. The second kind of feels like it disappears up its own ass a bit, where half the character behaviour is about, I dunno, like consciously playing out anime cliches in real life. Nobody does that. So like mainly I just couldn't take the whole "Madarame harem" arc seriously, especially when it went on. And on. And on. And on and on and on. It was stupid, didn't feel like real-people behaviour, and it got boring. And it took over the manga, so just not liking that arc was enough to make the manga kind of dislikeable. It wasn't terrible because there were still lots of great bits, but the storyline just felt really forced to me.
(actually come to think of it there is one character I really disliked as a person, and other people never really telling her where to go made me kind of dislike how she worked as a character: That girl who was always smirking as she tried to maneuver people into embarrassing situations for her amusement. What a horrible bitch)
