The whole "remastered" series was a nice excuse to buy the TOS DVDs
, and it was great fun to watch these stories again. They stood on their own two feet without the viewer requiring any prior knowledge.
One thing that struck me though, the Klingons of TOS seem to be much cleverer than those of the films and later series. The original Klingons are very devious and skilled at strategy, like evil opposites of Kirk. They're aggressive, but not in a stupid way.
But then in the films and TNG onwards, Klingons seem to gradually become closer to space cavemen. :/
I'm not saying it was a 100% change, some new series episodes were better than others, and Undiscovered Country had some very intelligent Klingon characters (especially Gorkon and Chang).
But in general, why do TOS Klingons seem cleverer than those in later Trek? Was there something about the new makeup that reminded writers of Neanderthals?
