Wait, but you compare the cost of animated show or a movie which is in its final, acceptable quality!
The cost of that $15 per 30sec is NOT FINAL - you'll pretty much end up deciding you want another take - either due to some inconsistencies, non-physical movements, or anything else, which screams "that's fake".
So the cost is most probably much higher; how much higher? We don't really know, as there are virtually no acceptable shows created by that tool yet (until there is something I don't know about).
