Marvel needs to release 2 types of superhero cartoons

Cartoon #1- Introduce younger kids (ages up to 7 or 10) to Marvel characters so they are familiar with them. My cousin is 3 years old and loves the new Ultimate Spider-Man cartoon. Now me, being a teenager, would never watch it as it is for kids his age but this cartoon has introduced him to characters such as Spider-Man, Iron Man, Thor, The Hulk and he loves the show.

Cartoon #2- A more adult cartoon on the characters for teenagers and young adults, hell, even regular adults. This show would focus on being true to the comics and relationships, emotion and being a good show for fans (I.E. The Spectacular Spider-Man which worked as a cartoon for young kids too as well as older people)

Since it seems that they take turns with this. They had Spectacular Spider-Man which older people enjoyed and liked but now there's Ultimate Spider-Man which is mainly for little kids. If they had two separate shows (TV-Y7 Spider-Man or other characters and TV-14) they could please both audiences without having to take turns. Basically one introduces kids to the characters and the other gives them the story that they want.
