Uh, as an Urusei Yatsura fan I'd like to clear up a misconception here. UY is not like modern romantic lonely-boy anime at all. In those kind of series, the main character is nerdy but kindhearted, and is inexplicably surrounded by cute girls who might dislike him at first, but they all end up falling for his simple goodness in spite of numerous misunderstandings and, er excuse me
>retches violently<
Anyway, in UY, Ataru is scum. He's selfish, perverted, cowardly, hypocritical, underhanded, and vile. All the cute girls in the show (along with all the boys too,) hate his guts. The sole exception to this is Lum, who he keeps trying to get away from. UY is pretty much non-stop pun-riddled slapstick comedy, and really bears no resemblance to the typical romantic fanservice-ridden 1 loser guy+5 billion lolitas lonely otaku bait that's clogging the shelves currently. I blame Tenchi Myuo for that shit.
Sorry for the insufferable nerd lecture, but when someone says that UY started the genre Love fuckin Hina is in, I feel all crawly. :{
