This seems to be marketed as a martial arts film, but it's really a love story with the necessary conflict and heartbreak. The kickboxing scenes are limited to ring events; arson and fights outside the ring are realistic and not cartoonish. I watched a Region 0 DVD with English subtitles; I could not tell, exactly, which audio was French, which was Chinese, which was Thai. Samuel Le Bihan sings in Thai! I read elsewhere that the Ramirez brothers are first-generation French of Spanish parents; maybe I'm a barbarian American, but I don't see where that's explained or hinted at in the film, unless it's the name "Ramirez." The actors all do a good job. A lot of the personal conflicts do not get resolved; how many do in real life? I am glad I saw this movie.
