In Tarantino movie, Django is a black Siegfried saving his Brunhilde, who speaks German flawlessly, from the clutches of barbaric white people who brutalize slaves.
The movie's biggest problem is its greatest virtue: the interpretation of black culture from a European cultural reference.
To make the inversion of values, the movie hides the true culture of blacks (which provided resistance to slavery in the past) and appreciates the culture of the white people who practiced it.
The resistance to the nineteenth century racial slavery based on ancient German legend (Siegfried and Brunhilde) in the background destroys the cultural memory of the enslaved out instead of retrieving it.
A people only conquest and keeps his freedom preserving their true heritage. And that is exactly what destroys Django.
The cultural racism in the new movie of Tarantino is evident. He did not study the true African culture through which slaves resisted slavery. If Tarantino had studied the movie theme (racism and resistance to slavery), he would realize that slaves did not fight against oppression valuing the culture of the oppressor.
The ideology implicit in the movie is that we can only fight against racism and slavery through European culture. This makes no sense, does not even have veracity.
In the deepest heart of Tarantino's work, there is a racist dragon awake. And he says to black Americans who visit the cinema to see Django: forget your real culture, you guys have no right to have one.
