Doesn't try to beautify things but shows wildlife as it is. In particular, you do see lions go after prey in concert and eat, and receive some insights into their techniques and general approach to the matter.
A misconception I had, for example, was that male lions don't really hunt but let the females do all the work. Wrong, as it turns out, they do get into action, just not that often, but when they do it's quite the spectacle.
A documentary probably suitable more for grown-ups than small kids, though, because, at times, the imagery can be graphic. As said, the doc tries to be authentic, to a reasonable degree, considerably more so than many others do.
