I was left imagining what could have been after watching this movie. It had some good parts, alot of mediocre parts and one or two bad parts.
I think having read Conn Igguldens books recently i was expecting more drama, but a lot of it was skimmed over in favour of the focus on the relationship with Borte, Jamukha and the khan of the Kerait. You never really get to see the drama and struggle of Temujin and family after being left behind when the tribe moved on after his father's death, and therefore his killing of Bekter looks more like it was done on a whim, or much of his childhood and the struggle to establish his new tribe once his family had learned to survive alone in the wilderness.
It also fell well short of the full Genghis story by ending as the Mongols approched China, which is really where he established his reputation as a great leader and warlord.
Ultimately i'm hoping that Mongol (and its 2 sequels) will be better or that a big studio will take on Iggulden's books and recreate them.
