Seegee:
The Karate Kid Pt2 was really a remake of 1, but set on Okinawa. I can see why they titled it Moment of Truth, because that's essentially what it was about. It all came down to that last moment in the final. Would have loved to see Elizabeth Shue spank him, though.
Well, I disagree on that...
The original motion picture centered on Daniel, both his issues with the school bullies and his 'love life' (which were somewhat interconnected), but IMHO "The Karate Kid II" centered on Mr. Myagi and his reconciling of old relationships from decades earlier on Okinawa.
Of course Daniel was involved in a challenging karate-style showdown at the end of the movie, after all he's the 'Karate Kid' of its title, but I didn't find that fight to be a critical part of the plotline.
Old-time comic book readers might recall that the nickname 'Karate Kid' was used by a member of the 30th-century Legion of Super-Heroes, predictably a martial-arts expert; I don't know if the character is still currently in use by DC Comics.
Daniel (Ralph Macchio) being soundly spanked by his girlfriend (Elizabeth Shue), that would've been great--perhaps she actually broke up with him (referred to at the beginning of "II") because he was spending too much time on martial arts, and he later had to accept a good butt-blistering from her to eventually restore their relationship.
It's an idea anyway...
