The inaccuracies bothered me. Like, why the fuck would Kublai Khan have the greatest engineers in the world working for him, and yet they get schooled by a teenager from Italy? On tech that Genghis stole from the Chinese like 60 years prior? Seriously, the Mongols were KNOWN for smashing walled cities. It was kind of their thing. And they make it seems as if there was this big period of truce of something between the Mongols and the Song. Kublai was fighting a guerrilla war inside their territory for years when Mongke was still alive. And all parties involved were well versed in the use of cannons and black powder, the cannons would have been way way more effective than those muskets that probably took half a dickyear to load.
But, nerdrage aside, it was an ok show. My only hope is that it inspires someone to do a better show about Genghis. Marco was kind of weak, but not as bad as I expected from the posts here. Fucking Ahmad, dude should have just been twirling his moustache the whole time, I mean seriously.
