This film is a remake of the classic Spaghetti Western "Days of Wrath" (aka "Day of Anger"), with Chang Yi in the role originally played by Lee Van Cleef. The basic plot outline and some incidents are the same, but too much is omitted and replaced with standard kung fu fare, and the strong ending of the original film is replaced by a standard kung fu ending. Too much weak humor is also added here; was it really necessary to have three separate incidents of unsuspecting people being given laxatives? Still, any fan of the original film will want to see this remake, and anyone who enjoys this film should try to see the original "Days of Wrath".
