it's the fact that's it's def in your face kind of sexual humor. and it's not much of humor compared to the way family guy or some other shows protray "sex". in a way other shows poke fun at it. this show kinda just i donno ._. i watched a few episodes and i really can't stand it. it's too much of the sexual content. -_-" i guess the kinda shows i like are like more "serious" in terms of the storyline. like they actually have a plot that sort of draws my interest. for example kekkaishi, soul eater (not so much anymore lol), hitman reborn, haruhi suzumiya (it was strange at first but at least it was less of the in your face kinda stuff and it was balanced out with someone who can at least had some sense ._. lol poor kyon), inuyasha (not so much sexual content but a few jokes with moroku (sp) srsly he needs to stop -_-"), cowboy beebop (was a bit sexual but yet again not as obscene except with faye, she was cool but needs to stop the butt showing <-<), FLCL (YES it was very SEXUAL but i had some laughs out of it, and it took me a while to understand some of it lol and i understood the series, and there was something more there. it just drew my attention and it got me interested i guess cuz it had some mystery about it (at least they were more properly dressed! lawlz XDDD), neon genesis evangelion (was a VERy good manga. loved the plot and characters <3 and this story really kept me on the edge of my seat a lot X3) and there are many others! i loved chobits too but some parts were just >_< *slaps hand to forhead* it was a subtle way to get the more "sexy" appeal of manga/anime to me i guess.
but i can see you're argument there though!
the "happier" anime i guess i speak of is like the more children targeted shows, like pokemon (jap.), miyasaki films <3 (really wish he could make anime ;~;), fantastic children (that was a beautiful work of art).
