I have to admit, speaking as a DC and Marvel fan I don't tend to follow that much on Daredevil comics in recent years, but I like where the show is going.
It's deep but not to the point where it feels pretentious, gritty but not too "Adult" like on HBO, based on particularly comic book lore while not going nowhere with it. (Gotham, anyone?!)
Is it violent? Yeah there is a bit of violence but it's mostly kept to a PG-13 rated level; Raunchy?... Well the humor is not too crude or shocking, and they do use the S-word once in a while (Which begs the question why is it inconsistent to censor that word in pg-13 rated programs or not) but it's kept at a minimum.
I know I've said before that I tend to have problems with superhero based things being too dark and dour, but Daredevil serves as a counter argument that that problematic trend, in which it CAN be dark but not to the point where it feels forced or even joyless.
Still on the first episode, but so far I highly recommend it. But again, be warned it still comes with it's own set of gritty material.
