Ultimate Spider-Man doesn't really talk down to kids, but it does talk to kids. From the start, though, the show was intended more for the 6-11 age group (the audience Disney XD wants the most) than anyone older. And the strategy appears to be working very well in that regard for the network. The only cartoons that really do that anymore are shows mostly backed by toy companies like Pokemon, Beyblade, Bakugan, etc. For other cartoons like The Clone Wars and Young Justice, the toylines are a by-product because they're studio-backed properties. The same would be true for a new Star Trek cartoon.
