Inconsistent but reasonably good. The protracted lead-in to the core of the film works surprisingly well as we get comfortable with the characters who will eventually be endangered. Primarily this movie deserves attention for bursting taboos regarding violence by and toward children in unsettling yet credible ways. I'd rather like to see a remake - a good remake of this could be chilling.
A Hung Kam-Bo choreographed fight is a beautiful thing. This early example in which he directs and co-stars as well is definitely a cut above the average martial arts film of the era; a bit more attention to story and character than usual plus, again, those astonishing martial dances.
