Dino Squad — yet another reason to stick to anime. (Via Tim Blair.)

To be fair, anime has its share of this. Let's remember the infamous Arjuna, the Earth Maiden. On the other hand, it's not always the straight party line. In J2, creators portrayed a school where kids are taught everything with a global warming bend: global warming texts in English, physics of global warming, math of global warming, literature about global warming, and so on. It was awesome because it was subversive.
