While it may not be as great as Chowder, it too actually does a very good job trying to save Cartoon Network from going downhill. The man who created Flapjack has worked on three of my favorite Cartoon Network shows such as the Powerpuff Girls, Billy and Mandy, and Camp Lazlo!
In fact, a lot of the crew who worked on Camp Lazlo! worked on Flapjack. The art is very creative, it's dark and realistic, it has more to it than just being gross, the grossness and disturbing imagery fits the setting of the show, and the characters are very well-written. Not to mention, the voice acting is spot on. True, it's insane, but what would you expect? It's actually something I prefer over Superjail! Heck, the creator of Gravity Falls worked on this show.
So, I was wrong about Flapjack being a horrible show. I really like Flapjack the way it is.
