But notice though that a lot of children tend to like things that aren't BLATANTLY "kiddie". A lot of kids were watching Attitude, listening to more "gangsta/edgy" rappers, watching Batman, Gargoyles, and Dragonball Z while playing Mortal Kombat and Street Fighter the next day when I was a kid.
We even see this now because kids tend to like the things they are told not to like as opposed to something that BLATANTLY SCREAMS "I'm Family-friendly please watch me!!"
All they really have to do is create a product that has colorful gimmicks and storylines that go into more "realistic territory" along with things that happen to appeal to children as well. This is why kids like the new Batman, X-men, Iron Man, and even Spider-Man films because it's found a fine line where it can be just as much for adults as it is for kids.
