The fourth chapter of the "Mad Mission" / "Aces Go Places" series is a somewhat odd mix of the slapstick tone of the previous entries with some violent and unpleasant moments. The result has enough chases, stunts and bumps to be recognized as a part of the series, but it still feels somewhat alien to it. The script is (as usual) weak, and for all-around action fans I'd say "Part 2" remains the best choice, but for martial arts fans this may be the most satisfying entry yet - there are more fight scenes than before and Sam Hui is surprisingly credible in them. The best thing in the movie, however, is the addition of the wonderful Sally Yeh, in a semi-action role. (**1/2)
