Wow, I forgot how Kamen...
Basically he just went to his work on the 'Die Hard' films and said to Silver/Donner "Here you go, I created this great Score for you, COMPLETELY Original Stuff" lol...
I mean, I don't mind when Composers use Cues from other film scores or pieces of music and insert them into other films but sometimes it's just TOO much. I like Kamen alot, he created some wonderful contributions to Cinema and I'm not bashing HIM so to say... It just seems lazy that nobody noticed (Or cared?) that there are major scenes where the great Score that defined THIS Action Franchise is substituted with the Great Score that defined the other MAJOR Action Franchise of the Era.
