An action-comedy combining elements from Sammo Hung's "Lucky Stars" movie series and Karl Maka's "Aces Go Places" series would have been incredible and potentially great. However, this movie did not meet that expectation, as it had no solid plot - just a bunch of silly, tasteless and goofy nonsensical humor one after the other, making the movie dull, repetitive and non-suspenseful.
The original "Lucky Stars" characters weren't in the movie much to begin with, and the rest of the actors weren't as memorable or remarkable as in the first three films. Jackie Chan and Biao Yuen were sorely missing from the movie, and Karl Maka and Sylvia Chang from the Aces Go Places movies weren't utilized enough.
The plot about Kidstuff (Sammo Hung) being asked by the police to investigate an international ammunition trade between two gangs appears to be rehashed from previous films and the subplot of the rookie cops trying to woo a female cop in a house they're sharing is the same ol' joke.
There some actions scenes here and there, but the bad acting and tasteless humor made this the worst movie of the "Lucky Stars" series.
