Like a manga for the strangest reasons?

I doubt many people will bother to reply, but oh well. So anyways:

Do you like or have liked a manga for something other than it's selling point?

Meaning that you like a particular series for a reason that is outside its genre.
For example, you like Naruto because of homages to Japanese Mythology and not the ninja action.

Here's mine:

Gantz - It's an action/sci-fi manga that mainly sells with its gratuitous violence and breasts, kinda like Elfen Lied. However, unlike Elfen Lied, Gantz is actually interesting and doesn't pretend to be deep.

Case in point, the reason I'm reading Gantz is because I want Kei and Tae to be back together again, because they're such a nice couple. Plus Tae is so cute. Dx

EDIT: They're back together again, and I'm happy. Now I just want them not to die.

Basically, I'm reading Gantz for the romance and not the blood and boobies, as strange as that may be.

(Seriously, breasts are practically a main theme in Gantz. >.>)

Yes, perhaps the Elfen Lied manga is deeper than its anime counterpart, don't know, never will. But all I could get out of the anime was "naked bloody lolis". Yet I could always see something past the blood and breasts in Gantz.

If I'm not very clear, sorry, I write these topics in the middle of the night. :<

And also, that giant naked lady monster was quite hilarious.

I started reading The Pet Shop of Horrors... because my friend showed me man eating bunnies in it. The manga does have lots of animals in it and all, but each story actually has something really interesting to it (some more than others and usually the ones where someone dies).

Also, Count D was an interesting character, but he might have been a selling point. Leon and D's interaction might have been one, too >.> but that was also quite interesting.

And the anime was nice and fast paced and.. you barely noticed the nudity in most parts because of all the blood, at least for me and some of my friends o.o

The drawings were also nice and kinda cool, but it's a manga.. so that might be a selling point, too.

I adore Gunslinger Girl. But I can't seem to find any more chapters.
I want more Petrushka.

I lost interest in Bleach after episode 60.

And I seem to be liking Darker Than Black because of Yin, although I'm not usually for personality-devoid characters.

I like Sayonara Zetsubou-Sensei more for the deepness of each situation than the comedy and fanservice that usually takes place in the manga.
