People like to worry themselves to death over proving how they aren't "racist." Black Americans at this end of the century are pretty heavily groomed by the system to be extremely sensitive of any possible conceivable slight.
Both of these folks will be delighted to take offense at the very mention of the name "Amos and Andy," whether they've ever actually SEEN any version of the show or not. A&A are the very SYMBOL of Hollywood racism, defaming the image of blacks. Supposedly.
I would take it that "Amos and Andy" represents (however accurately or not) a broadly caricatured representation of regular poor black folks. You could make it out to depict them as foolish, but no more so I say than do shows aimed at poor whites. I have in mind for starters the Beverly Hillbillies.
Nor are the depictions of Amos and Andy harsher than those of Ma and Pa Kettle. Now THERE is some negative stereotyping.
But hey! It's just a joke, and not particularly mean. Amos and Andy as characters aren't deep, but they're affectionate and good natured, just a couple of regular joes trying to get by. Doesn't strike me as much of a hate crime.
Oh, and they're pretty damned funny, too. Note that this bears the same screenwriter's name as several Marx brothers classics, Bert Kalmar. This ain't quite up there with "Duck Soup," but it's pretty funny stuff. The kingfish and the lodge stuff put me in mind of the Flintstones' "Water Buffalo" lodge, and the silly rituals and blowhard leaders trying to puff themselves up to look like alpha-males.
Also, this film stops for some straight up film time for the most righteous Duke Ellington orchestra. There is very limited film available for any musicians of the era, especially black ones. This part alone justifies the film's existence for me.
C'mon, loosen up folks. Eddie Murphy makes 10 times more stinging jokes. At least Amos and Andy weren't pimps or dope-dealers or crooks.
