Let's be honest, almost all of the 1 star reviews are because of how the Mayan's are depicted and stem from a lack of historical knoweldge.
There seems to be the misconception that the Mayans were peaceful and didn't sacrifice humans... which reminds me of when my wife and I went to visit her family in Guatemala where the high point was really watching the American tourists swim in pools of water that probably had the bodies of thousands of sacrificial victims at the bottom... mostly 14 year-old boys.
Yeah, no way I would get in that water, but then I know what's beneath it.
