I'd say a mix... Kinda like Clone Wars. Clone Wars really had an adult feel, but my gf's kids really enjoyed it immensely. I remember her youngest laughing his ass off at the Clone's being smacked around by Assajj in the forrest, and he liked Durge with his biker droid army too.
It's nice when adults and kids can enjoy something simultaneously... Unfortunately Lucas himself can't maintain a balance like that.
The Batman Animated Series was definitely aimed at both though I believe. Adults could get into it seriously, but it wasn't too violent for kids, it had humor both could follow and laugh at... That's good stuff.
Kinda like Toy Story I think... To use a comparison. But a lot less funny than Toy Story.
