This film recently came up on NowTV and thought would give it a try without knowing anything about it. Very glad that I did! If you think you would enjoy an insight into a brutal period of medieval history not well known in the west with a mix of realistic battle scenes and court intrigue (and you don't mind subtitles) then I could recommend this. Central to the story being the kings aides who have differing advice for the King on how to deal with the invading Chinese army against a backdrop of a society with very distinct rich and poor divide where honour is sacrosanct. The film captures well the bleak remote location of the fortress while the combat is refreshingly devoid of the extensive use of cgi.
