Doug the show has real family values. the many situations that doug gets into can definately teach a kid, which as at an impressionable age, some true values, ethics, and how to solve problems in everyday life.
now is it the most entertaining cartoon ever? no.
but just because of its values and teaching what is right in a completely non-denominational manner, I can say that it deserves my two thumbs up, and yours too.
