Have you ever noticed how several animated series were preceded by standalone Christmas specials? Peanuts, Alvin and the Chipmunks, The Raccoons, The Simpsons, and South Park all started out this way. While not animated, the Trailer Park Boys Christmas special was a standalone prequel. The shows that followed these Christmas specials are quite different in animation, character development, settings, etc. In contrast, the Inspector Gadget and Sonic the Hedgehog Christmas specials, both served as belated series finales. Pretty cool, huh?
