Passion Unbounded is one of those rare movies you want to forget you saw. A mixed up thriller about a serial killer (who happens to be female)and her deadly exploits. Carrie Ng, one of the beautiful assassins in the movie Naked Killer is wasted here in this wretched exploitation movie which tries too hard to emulate Basic Instinct. It fails to work on several levels. As a thriller, the movie is laughably inept..the plot is so convoluted and implausible that you can only shake your head in disgust. Most of the characters are so two dimensional you can see right through them. As an exploitation flick this movie doesn't even titillate much less stimulate. Not at all in the same league as other Hong Kong movies of similar theme such as Dr. Lamb and The Untold Story. Carrie Ng fans should stick with Naked Killer, a much better crafted story. Avoid this movie with a "Passion Unbounded".
