Good attitude.
Here's my unsolicited opinion...
There's a niche for everything. "Edgy" cartoons simply have a vocal niche - people who want to show how hip they are. "Ducktales" & "Little Lulu" types are, by nature, not well represented by any means except passive ones (like watching your hits). To sell to a 10-year old, you've got to remember what you liked at 10 - this is tough because you want to remember yourself more mature and hip than you really were. (At 10, my sensibilities foretold the kinds of things I like now: adventures, mystery, gadgets.)
Once you've found your niche - work that baby. If you can get a loyal audience, you're in.
