The late 2000s is generally considered to be a dark age for Cartoon Network. Indeed, as soon as Stuart Snyder took over, he introduced a mandate of no weird stuff (though shows like "Flapjack" managed to sneak past that rule). What's more, the advent of miniseries made the 2010s a truly special time for Cartoon Network. And while the miniseries era sadly didn't last long and was mostly dedicated to "Adventure Time" spin-offs, we did get a brilliant miniseries that remains one of the best animated shows ever made. That, of course, would be the 2014 fantasy miniseries "Over the Garden Wall."
