Creepy Banned Children's Cartoon: Who is the Intended Audience?

"Creepy Claymation: Molding Young Minds"

This one's been on youtube for awhile. Called a 'banned children's cartoon', it is a claymation scene of 3 kids and a guy who looks like Mark Twain and their adventures going through a portal. They meet a creepy figure who identifies himself as both an angel and satan and who then proceeds to demonstrate the pettiness of humanity and the meaninglessness of of existence.

Definitely way too heavy a topic for a children's program! The creepiest parts for me are when the devil-thing's mask twists in suppressed rage, and later at the very end when the Mark Twain figure's face falls as if he knows that the devil thing's words are true....
