I....I actually liked the PPG ;_;
I don't think it was a show for girls at all (MLP definitely is). It starred girls, but those girls were involved in a lot of action (which appealed to boys as well). The violence was on a higher level than anything else marketed towards girls since, probably.
This. PPG were badasses. And as far as cleverness... that Beatles reference episode was pure genius.
