Continuity mistake: During the "exciting" conclusion, Investigator Natsuo runs toward the villain's vehicle, jumps, and kicks through the windshield. Besides the fact that there are some poor special effects at work, watch this quick shot closely. As he is flying through the air in that split second, the villain's car changes colour! It is quite obvious, as the car goes from a dark red color to dull grey.
Other mistake: Watch closely as Investigator Natsuo kicks through the windshield and kicks the villain in the face. The villain's head caves in like it is made of cardboard.
