The film hasn't been released here yet, but I've already watched it in the Russian dub. At first, I thought I would write a lot... then I decided not to bother. So, in short.
Beautiful, with a more or less interesting concept... a simple plot is turned into complete nonsense due to pretentiousness and excessive complexity, especially when it comes to the characters. Even I, a fan of historical Eastern cinema, was disappointed by this film. And, of course, the realism is at zero.
Only General Yan and his son evoked sympathy; they are the only normal people in the film. This is symbolic, considering their role in the plot. And in the first half of the film, I felt sorry for the main character, but then... who likes cheaters with immortality?
After half an hour of watching, the music starts to irritate. It's very monotonous, and often it interferes with the viewing. Is this some kind of Chinese folk music concert?
Zhang Yimou disappointed me.

To specifically explain why it's nonsense, I would have to retell most of the plot and give examples, so just take it as a fact.
