If you have seen the trailer, you can skip the movie

Rating: 4/10 (14 November 2016)

The movie is constructed of interminable fight scenes strung end to end. They use one special effect over and over. The fighters appear to have the magical ability to almost turn off gravity. They can take long slow motion leaps or run up walls.
The net effect is boredom. I fell asleep over and over.
The characters are driven by infantile revenge and even more petty motives. They belong to a warrior cast who kill each other for amusement. When someone is killed in this game, they blame the evil killer rather than their participation in the game.
The fights involve hitting and kicking each other. These blows have absolutely no effect on the opponent, even when endlessly repeated.
There one fight scene in a restaurant and one in a tree canopy that shows more imagination. I found it hard to keep track of who was fighting who and why.
There is a bit of comic relief, reminiscent of The Taming of the Shrew between a handsome, good-hearted, desert-dwelling falconer and a pretty young woman who preferred adventure to a stifling life in an arranged marriage.
The majority of the fighters are female. I think at least one of them was over 40 and another over 60. They were fully athletic. I expected the fighting to limit actors to their early 20s.
Others have recommended this movie. They must have a much higher tolerance for repetition than have I.
It is in Chinese, with English subtitles. In one scene, a character is surprised that the "Jade Fox" villain is female. This seems odd because they have been referred to her as "she" in the subtitles. In Chinese, they use the same pronoun for he and she, so that pronoun did not give her gender away.
