I'm pretty sure most of you mean "I want them to rerun this again" not so much shows that should come back with new episodes. A lot of old shows I'd HATE to see come back because they just wouldn't be the same (or worse, poorly designed remakes).
However, there is one thing I'd like to see back... not so much as new episodes or reruns of, but rather an entire genre of programming.
I've said it before, but Disney did a world of good with Phineas and Ferb. I'm so far liking their plans for Marvel action shows, but they need something else. The next big Ducktales like idea for a cartoon show. Something we would have seen on The Disney Afternoon. An action comedy... something that doesn't feature kids going to school (like their ABC Kids/One Saturday morning line). be it from a movie, or just based on classic characters or Disney comic books. I'll continue to say a POTC cartoon was a huge mistake for them not to make, especially at the height of its popularity. And now that they don't have ABC Kid's Saturday Morning line up (*&&%^% Litton Adventure Weekend), they don't need to make shows TV/EI to recycle them on another network to satiate the FCC standards.
There's limitless potential for a new Disney cartoon series. Like I said, check out the Italian Disney comics... Wizards of Mickey, Ultraheros/Duck Avenger, Double O Duck... like I said. Mickey, Donald and Goofy need another project besides Mickey's Clubhouse. Or better yet, a new Scrooge McDuck series, closer to the original comics. There's so much they can do do, yet they gave us Fish Hooks.
