World class concept, acted with superb performances by Cinematic Giants. This movie serves as a warning - (as though more warnings were needed from the history of the course of the often disgusting proclivities of humanity) - of the dangers of shortsightedness, selectively-blind sightedness, and the like. It also points to the importance of acknowledging that we don't know, when, in fact, we don't know. It - perhaps more importantly - points to the importance of acknowledging that, even when we are "pretty sure we know", we may not know for sure. May we do better as a species. Thank you for this movie, and I wait with baited anticipation for the sequel.
