For fans of the first two movies, such as myself, this movie will be a decent watch, mostly thanks to the returning characters of David Sloan and Xian. Both Sasha Mitchell (David Sloan) and Dennis Chan (Xian) have a limited acting range but their chemistry together is quite good and work well enough as a buddy duo, similar to something like Mel Gibson and Danny Glover in the Lethal Weapon series or Chris Tucker and Jackie Chan in Rush Hour, but obviously to a lesser degree.
There's two drastic changes that fans of the series will have to endure, one being that this is more of an action/thriller than it is a martial arts movie. Sure, there's still plenty of kickboxing in the movie, but if the poster for the movie wasn't enough of a hint, David and Xian go around shooting and murdering plenty of bad guys. The other change are the type of villains we have this time around. In the first two movies we had Tong Po, who was a very scary fighter, but in this movie our main bad guy is Frank Lane, played quite well by Richard Comar and he is not at all in the slightest someone that can fight. Then in a lesser role, the other bad guy to consider is the fighter that Frank Lane manages, who comes nowhere close to being as intimidating or interesting as Tong Po was.
I'm sure this movie had a limited theatrical release somewhere, but it does have a certain straight-to-video vibe about it and for a movie of that nature, it serves well enough to those who want a 90's action movie with guns, fighting and a simple plot. I'm a fan of Sasha Mitchell and the Kickboxer series so consider that my rating for this movie is higher than what most others would give.
