Three things make this Tom&Jerry cartoon stand out from the crowd:
- We see more of Mammy Two-Shoes than ever, not just her face but also a bit of her social life.
- It is one of the relatively few cartoons where Jerry doesn't get a total triumph at the end.
- It is filled with good 50's jazz music.
And it is even more. Tom has a whole gang of friends, and the cat(s)-vs-mouse chase, although basically the same as usual, is filled with gags around musical instruments. Jerry is even reshaping into the musical instruments he hear.
Finally, it is one where censorship has done most work, with two revisions, first replacing Mammy Two-Shoes voice with a smoother, bland voice, and then redrawing a lot of it to replace her with a skinny white girl. And every change made it worse (except possibly replacing cards by dancing). I find it hard to see how Mammy Two-Shoes could be severely racist where she is clearly the master of her house, not always obvious in other cartoons, and replacing an overweight middle-aged black woman with an almost anorectic white girl is hardly a step forward, limiting both age, weight and skin color to something considered "right". Is it a good move to remove strong, independent black women from the screen? I know the voice is cliché but nothing more, and many new movies are worse (the new Ladykillers, the Rush Hour series...). If Chris Tucker can make fun of "black language" why can't Mammy Two-Shoes?
So it has all the action and gags of an above average cartoon, but with these unique features on top. Not mind-blowing unique but quite significant.
