This film was just an abomination of information.
I started watching this movie with the expectation of a good film about the African heritage. But this was NOT what I got. Rather, this movie is some militant, black power propaganda.
The film maker does not know the difference between race and culture. The African continent, has a lot of different cultures. The cultures in the west of Africa are entirely different from the cultures in the East. But the film maker just grabs them all together and calls them 'black people'. He claims inventions and doesn't contribute them to the Nigerians, the Somalians or the Angolians. No, just black people seems to be enough.
None of the claims in this movie are substantiated or backed up with sources. The film literally claims that the piano is invented by black people. While it's documented that the piano as we know it today, was invented in Italy... And that the piano has evolved from the Harpsichord. An instrument invented before the year 1400... I know instruments, so I know for certain that this claim of Hidden Colors is more then just ridiculous, it's outrageous!
Furthermore, the film claims that the clock is invented by black people. Which is also an outrageous claim. Clocks were invented all over the world in the form of sundials, water clocks and candle clocks. The first mechanical clock is invented in China, around 800 AD. But the film maker just says: Nope, black people did it.
To me, this shows the true goal of the film. It is not to inform or to educate. It is not to inspire or to entertain... It's to arouse the militants. I would call this film straight up propaganda.
The high rating this movie gets on IMDb, is obvious but very undeserved. In my views, this film is a farce... A joke... Laughable... Don't watch it if you want to enjoy African cultures, don't watch it if you want to learn or to be entertained... But do watch it if you are a militant or sympathise with the Black Panther movement.
