Dot and The Kangaroo/YMMV

Original film

 * Nightmare Fuel: the bunyip song, the hunters.
 * Tear Jerker: The ending! Even if you don't cry, you can almost feel like you're going to cry.

Sequels

 * Anvilicious: The anti-racism moral of Dot in Space.
 * Ho Yay: The round and square princes in Dot in Space. Especially with the whole Romeo and Juliet thing they have going on, as well as how effeminate the round prince is.
 * Nightmare Retardant: The Bunyip turns out to be not nearly as scary as the first film made it out to be.
