Hmm. Whenever I see that expression in the context of a comedy, I assume they mean some non-PC elements are present. Maybe there are some jokes that would need to be modernized, but IIRC (saw it decades ago), it was mostly positive (like the Black family that adopted him is portrayed as poor, but nice and loving, right?)

OTOH it was a moderately-budgeted, somewhat clever comedy, those have trouble getting made today.
