Warlords is a beautiful film, the sets and the costumes are very rich and the acting is superb, especially Jet Li, Andy Lau and Takeshi Kaneshiro. There is a lot of blood and guts (and mud) in this film, some great battle action sequences, but it does not seek to glorify war, but shows it for what it is, raw and bleak. The story opens in china around the year 1860, during a time of rebellion and chaos, so there is a mix of traditional sword fighting and archers, verses guns and cannons. I don't want to give too much of the plot away, but if you like films about heavily outnumbered forces fighting against a larger and superior foe, then this is for you!
I did not see anything wrong with the quality of this blu-ray film it is spot on and sharp, it is shot artistically and the film grain you see in some parts of the picture is to do with the types of film stock they used and the lighting and lenses etc... in other words it was intentional. The only movies that do not have any film grain in them are 100% computer generated movies, because they do not use film stock to create the movie, except when printed onto film stock to be projected in a movie theater - then they have film grain!
So don't let film grain put you off buying this Blu-Ray, it just makes the ride and the world of the warlords more gritty, more human. It also creates a stark contrast between the warlords world, and that of the far removed world of the Empresses clean, orderly palace, in Beijing.
