I'll actually have to second King of the Hill, for any age groups. It's on every weekday from 10-11 PM on Cartoon Network's adultswim block. At its core, it's a show about the innocent flaws of humanity in modern society. It's a masterpiece of deadpan comedy. And the show will grow on you. Although it may look dull, between the main characters, the show covers conspiracy theories, clinical depression, sinful affairs, early adolescence, proper work ethic, neglectful parents, and the mid-life crisis. Hank Hill is also a fascinating character. A red-blooded American, who was rightfully voted one of the wisest character's on television. Here's a deeply conservative guy, who is beaming after meeting Jimmy Carter. He looks him in the eye out of respect, because "you're a man who ran this country".
Speaking of adultswim, their nighttime block is really shaping up. Brief history: Ted Turner wanted Cartoon Network to run more mature animated programming, decided to use recycled Hanna Barbera footage. The result was Space Ghost Coast to Coast, which was later spun-off into 3 other shows, included Aqua Teen Hunger Force. These shows comprised the original adultswim nightime block, which now airs from 10PM-6AM every night on Cartoon Network.
Anyway, in my mind, adultswim's programming has actually set a few records. Starting with,
Most Disturbing Animated Show
Moral Orel is a claymation show about christianity. Or so it appears. In reality it's about a dysfunctional christian family centered around a naive little boy. A very dysfunctional family. Within one episode, Christmas begins, but there are no presents under the tree because the town's minister hints during a sermon that he knows Orel's little brother was the result of an affair between his mother and an unknown man. Orel's dad is furious and leaves, which makes the mother enter a deep depression, to the point where she never buys Orel or his brother christmas presents, nor makes them breakfast. Meanwhile, Orel asks where his father is, but the mention of his father makes his mother furious, and she sends him to go spend Christmas with his dad, away from her. Orel finds his dad drinking inside a bar, who in a drunken state, is now holding hands with the town's well-known homosexual bachelor. Saddened by his bleak Christmas day, he slumps down onto the sidewalk. After a couple minutes, he checks his watch and rejoices when he finds that 3 hours of Christmas still remain. You watch his optimism gently fade as he paces in the cold, still waiting for his father, who is either yet to notice him, or too neglectful to care, to take him home and celebrate the last minutes of Christmas. But Orel still waits...and the camera fades out.
