You will immediately notice: this story is "El Mariachi". Every detail is there, even many dialogue lines. The strange thing is, this film is listed as produced in 1990. El Mariachi is listed as produced in 1992.
Now everybody should know that Reservoir Dogs was a shameless copy of City on Fire, see "Who Do You Think You're Fooling? (1994)". But this one being the original and El Mariachi the copy? I don't think so. I rather guess this is the remake and should be dated to about 1994.
It certainly hasn't got the style and verve of El Mariachi, but still is fun to watch. If you like Hongkong-Style action playing in Mexico with a definitely chinese touch to it, this one is OK. 6/10
