If only someone would promise me that this is the last time I will see a hyena stick its head up a dead elephant's ass.

A dead elephant, the African wilderness, and nature taking its course. As simple as it sounds but incredibly interesting nevertheless. Seeing how such a beast can be reduced to nothing more than a puddle in under a week - and the variety of creatures that contribute to this - is so compelling you're left wanting more than the 100 minutes allow. Not perfect (e.g. the 'camouflaging' of the equipment isn't enough for the wary vultures) but still utterly fascinating (and at times incredibly gross!).
