Both terrifying and fascinating are the words that sprang up in my mind as I was watching the movie.
It's fascinating that the record of atrocities made to humans and animals in Africa existed already in the sixties. Just as those atrocities were happening. Today, fifty years later, we are only made aware post festum that something like that was happening and happened, but it is like some distant point in the past. If you think Iraq war in the nineties was the first 'live' feed of (war) terror from the other side of the world, think again. And try to find this movie. The movie maybe is not 'live' feed in the most rigid sense of the word, but it is a contemporary document of something that shouldn't have happened. And, what is worse, is still happening today.
And terrifying? Well, you just have to see the movie.
