From the loud, confident opening chords of the famous "Dragnet" theme music, I was filled with confidence that this 1987 "Dragnet" knew what it was doing. My confidence lasted several seconds. Then the original music segued into some kind of dreadful disco rap un-music, and my heart sank. How could they? How could they possibly make a movie called "Dragnet" and think that anything had to be done to the music?
