There are plenty of all ages books that pull of good stories. In fact, Bone is one of the greatest stories in all of comics. But Darkwing Duck is very good, the Marvel Oz stuff, Stuff of Legend, Mouse Guard, Billy Batson and the Magic of Shazam, Amulet, Chimichanga, Usagi Yojimbo, etc.
I think we all too often confuse All Ages with kids. For me an all ages book fails if it forgets to have a story.
