Oh, don't get me wrong. When I say it's my least favorite genre, I'm not saying I don't like it. I like pretty much every genre as long as they're done well really, it just so happens romance is the genre I'm the most picky about. It needs to have good characters or I get bored rather quickly. You mentioned I"s, that's one of those I didn't like much. Same for Video Girl Ai. Katsura's MC are too insufferable, and the girls aren't that great. Let's not mention how slow progression is too.
Ironically, I really like To Love-ru despite the MC being similar, but that's because the girls are amazing and the focus is more on comedy and boobs than romance
Everybody seems to hate Citrus, but I don't think it's that bad. The gorgeous art certainly helps, and at least the author tries to make stuff happen.
Recently, I've read Gekkan Shoujo Nozaki-kun (really great), Cage of Eden (very meh) and I'm currently on Area D. As for anime, I'm watching Touch.
