Despite Martin Scorsese being the executive producer and Ray Liotta having a role, "Revenge of the Green Dragons" doesn't seem to have received much of a theatrical release (if any) in North America. It doesn't take long to figure out why - the movie simply isn't very good. I'm not saying there isn't any merit to be found. Some of the acting by the largely no-name cast is fine, and directors Wai-Keung Lau and Andrew Loo do manage to inject a little stylishness despite their low budget. But for the most part, the movie's low budget does show, particularly with the extremely tight direction - I almost suffered from a case of claustrophobia with everything so closely filmed. But the movie also suffers script problems. None of the characters are fleshed out enough to give us a good idea as to their backgrounds or what they are thinking or feeling. I simply didn't care one way or another about these guys. As a result, the movie becomes extremely tiresome very quickly, and you'll be impatiently waiting for it to come to its end.
