Who says 5 year old will see it? The network that is going to buy the show. In the US the only market for animated shows are adult comedies and shows aimed at children(even if adults watch). Pretending that the US will suddenly adopt Japanese tastes and accept and adult animated drama is just wishful thinking. And while the TAS may have been based on reality the whole concept of the uncanny valley is that there is a valley in the believability graph just before the image becomes lifelike that it makes it harder for people to accept. TAS is so far from that valley point that it has nothing to do with the discussion. If you don't know what the uncanny valley is, then I don't know why we're even having this debate.
