I will add that it was TNG (And Ron Moore specifically, thanks to his reading of John M. Ford's TOS novel "The Final Reflection") that came up with the Klingon concept of honor. Before TNG, the TOS and STIII Klingons had no such concept.
Exactly, which is another point of proof that when some fans decry nuTrek's lack of authenticity, they are in fact expressing their frustration that it is not more like TNG.
