Discovery did a pretty good overview of his life and career a few weeks ago. It leaves out a number of details and focuses more on his military abilities, but it definitely is not a hack job. Most histories of him sound like "George Bush, as told by Al-Jazeera with special reporting from Osama Bin Laden" would. This one doesn't and it's worth watching.
I saw it while looking at the tv listings on the guide
channel, but figured it'd be terrible & didn't watch it.
One thing I do know (military wise) is the Mongols had
multiple types of arrows, which I thought were intriguing
(& beautiful in a certain way). Some were meant to whistle
while others were (of course) meant to inflict injury.
