There are many historical distortions in the movie. Biggest fiction is that Ablai Khan and Galdan never fought each other (Ablai Khan was born in 1711, where Galdan died in 1697). And Zhungars are not conquered by Kazakhs as shown in this movie! During Galdan's rule, Central Asian countries were no match to Zhungars-Mongols (even Khalkhas-Mongols).
The movie, itself is OK to watch. Just remember that it is a historic fiction movie.
