I'm not overly familiar with Tsukasa Hojo's original manga, but I have seen the original anime a long time ago. As adaptations of the source material go, Wong Jing's City Hunter isn't really the most faithful, it tones down a lot of Ryō's antics to fit with Jackie's style of humour and image but offers in its place a genuinely great movie that doesn't repeat a lot of the mistakes of American anime adaptations by trying to make it gritty, it's bat shit insane in the best way possible. It's also the best adaptation of Street Fighter this side of Future Cops, who doesn't wanna see Jackie Chan dressed as Chun-Li?
