That has nothing to do with my point.
Parents watch the same show as kids because:
a) a parent worth his salt would let them watch TV unsupervised;
b) they have to keep them busy somehow anyways.
It's not because they might have some kind of interest towards the show. Get over it and realize that what you're are gleefully watching is, indeed, just a show aimed at children. The fact it comes from Japan doesn't change this proven fact in the slightest.
