I remember having seen this on TV as a child some years ago, before cartoons of this sort were taken off the air as examples of things that were not air-worthy, along with the likes of "Amos-N-Andy", and a number of other films and shows whose proper place was the trash-bin.
To simply dismiss a cartoon such as this as being "not politically correct" is to vastly understate the case. It also demonstrates a certain naiveté and a lack of sensitivity. There is a tendency to gloss over this racism as " a product of its time". Mis-perception and deliberate mis-characterization of a group is never a "product of its time", it is a product of a particular world-view that does not die off very easily, and which persists in one form or another to this very day.
I ran across this appalling example again recently, this time in my maturity and not just looking to be entertained, as I was when I was a child. It is now apparent that the world also was watching this mess and forming their opinions based on what they saw, and those perceptions, too, die with difficulty.
Popeye, adrift at sea on a raft, eventually comes to an island which, it turns out, is inhabited by cannibals. Of course, this scenario is an automatic set-up for that which is to come, in terms of screen logic. The native population is replete with the typical stereotypes...bones in hats, cooking pots, cook books on "How To Serve Your Fellow Man" by IMA Cannibal. It was a disgusting and difficult watch.
And, of course, Popye prevails in his usual form, making the 'noble savages' submissive after 'showing them who's boss'.
"Salami, Salami, Baloney", declare the natives in obeisance after Popeye has lorded it over them in Tarzan-like fashion.
What could they have been thinking of when they made cartoons such as this?
This is one that has no redeeming value, and it's good that it is banned, and should be out of circulation for all time, along with cartoons of a similar bent.
