So what does one learn from Mel Gibson's latest movie, apart from the fact that good films can be made in dead languages and without top stars?
A few things, but still valuable. Such as distinguishing a historian from an ideologue. The former gives you all the facts and puts them in the context of time and civilisational development while the latter always omits the context and if there are facts that counter his ideological view of events, you can be certain he will supress them. For decades students learn from liberal-left historians about how great and ancient civilisations of Maya and Inca were destroyed by bloodthirsty Spaniards which killed millions and plundered everything in sight. Those historians would never present some facts that might have changed that interpretation. It was left for Mel Gibson. He revealed to the general public that the "great civilisations" were built largely on slave labour, that people were forcibly taken away from their homes nad loved ones and sacrificed to pagan gods for sheer amusement of the masses and that the survival of the fittest was the life moto, by and large. So what was it so bad that the Spanish brought with them that wasn't already there?
The other thing you learn, after you are aquainted with the facts Gibson presents, is that Hegel was right. He once stated that everything that collapsed throughout the course of human history deserved to collapse. At the end of the movie, you can't help but agreeing with him 100%.
