Long time fan tired of old time schtick

I'm constantly looking for a comic that delivers a dense, mature, complex story.
A comic who's content is the rival of any renowned prose work. An "adult"
comic. A comic "for the masses", that is, for nonfans. And as much as
I enjoy the comics I've found, they rarely fit this description. The Oni Press
books are definitely non adventure genre, and they are widely accessible, but Scooter
Girl and Blue Monday are still comical stories about teenagers. Scott Pilgrim is
loads of fun, made more so by the round iconic art style, but in the end it's also
about young people dating and throws in some over the top fighting scenes. Mind
you, I gravitate toward the science fiction and adventure stories and take great
delight in Promethea, Tom Strong, Top 10, Planetary, etc. but what audience do they
strive for? Isn't the bulk of the crowd still in their 20's? As you all know, I'm
NOT in my twenties. Isn't there a comic or comics that I can truly claim as written
for my age group?
Granted, "dense", "mature", and "complex" are subjective
terms and difficult if not impossible to define. I would put Blankets in this category
but hold it in question because the main character is in high school. Goodbye Chunky
Rice is similarly layered with meaning and even more poetic and touching as a story,
but is it helped or hindered by the iconic art style and anthropomorphic characters?
They say Maus is that much more accessible because it is anthropomorphic. Is Maus
the best we've had to offer the world at large?
Perhaps anything by Los Bros Hernandez. The art is elegant and the stories edgy,
complex and hold nothing back, and they cover a wide range of characters in all
stages of life.
Of course there's a separate track in the artistic merit of a comic. Chris Ware
offers brilliant visual experiences but leave something to be desired in the storytelling,
I think. Is is enough that a comic be visually complex?
Discuss.
