This is where it really goes downhill from here on out! Ostracised villain John Kreese attempts to gain revenge on Daniel and Miyagi, with the help of a Vietnam War comrade, the wealthy owner of a toxic waste disposal business. The film stars Ralph Macchio, Pat Morita, Robyn Lively and Thomas Ian Griffith in his film debut. Some would say this installment is just a rehash of the originals and in this case they’re right. Along with an uninspired story about a bonsai shop, campy villains and the leads feeling kind of tired up to this point. This series has run its course…until next time. An unworthy recommendation for the fans!
