Although it's quite likely that some artistic liberty has been taken with the facts, I viewed this with my "general state of affairs of colonialized African countries" goggles.
In that regard, it's a gripping tale that shows some of the horrible footprints left behind by colonialism mixed with other pre-existing tribal aspects of the local societies, not to mention the Cold War. That indictment is what stood out when I watched it, and it's eye-opening for those who've not lived in Africa.
Since this is a review of the DVD, and not just the movie, my only disappointment is that those of us with HDTV/widescreen capable TVs/projectors will notice the poor quality of this DVD. I watched Lumumba for the first time at a film festival a couple of years ago, and was looking forward to having a good quality copy on DVD.
Unfortunately, it's been *letterboxed* to shrink the widescreen format into a 4:3 frame. I wish they had used a true anamorphic widescreen transfer that would make fuller use of a 16:9 aspect ratio/resolution. In that sense the cover text "luminous new widescreen transfer" is misleading.
At least the Special Edition is subtitled, and not dubbed or censored (from what I've read of the other version), so that's one plus for this specific edition of the DVD.
