Sealab 2021 (Cartoon Network)

SEALAB 2021 is a quirky animated cartoon for teens and adults that's based on the 1970s Hanna-Barbera children's cartoon Sealab 2020. Combining footage from the original show with some original animation, the series follows the strange, sometimes-violent mishaps of an underwater crew of misfits. To explain the transition from the show's original, innocent version to its edgy, mature update, the storyline introduces a gradual insanity taking over the crew of the Sealab -- a collection of professionals that includes a marine biologist, engineer, and radio operator. The motley crew regularly encounters aliens, evil robots, amorphous monsters, and other strange entities -- all while undergoing personal crises like brain tumors; on-again, off-again sexual relationships; and murder plots. Many characters are supremely idiotic, particularly Captain Hazel "Hank" Murphy (voiced by Harry Goz) who's far from an ideal leader and often seems oblivious to what's going on around him.

The show's humor is decidedly edgy; some might say it even pushes the limits of good taste. For example, in one episode, the crew wraps a child who is part-human and part-dolphin in raw meat to lure a monster away from everyone else. The crew refers to the boy with a variety of colorful, derogatory synonyms for "fat." Other episodes feature jokes about sensitive topics like affirmative action and disabilities -- including one chair-bound character's exhortation that he's not crippled, but lazy. Obviously, situations like these are meant to be jokes -- perhaps even spoofs of other shows where the prejudices are more underground. But not everyone will find them funny.
