Although I am a massive fan of John M Ford's "The Final Reflection", I have recently been pondering how to define a TOS Klingon purely from what we see on screen -with especial reference to Errand of Mercy, Trouble with Tribbles & Day of the Dove. They seem to have a very pragmatic, strict and controllling society. Everyone from Planetary Govenors to ordinary starship crew are watched and monitored. Although, the three main characters that we saw are quite dissimilar in character from slimy-charming-dictatorial to sneaky-confrontational-legalistic to sorta paternal-aggresive-pragmatic. So there does not seem to be one all controlling monoculture thing going on. Maybe it is more a case of success in a greater position allows for a little independence of thought - as long as the line is mostly toed? They all seem single minded, and not very sympathetic (!!!), and there is definitely a strong sense of being driven to suceed, and that the end justifies the means. However they seem to have a lot of resource poor worlds (or is that just propaganda to motivate the troops and justify their conquests?) which drives them to expand. What else would you say makes a good TOS Klingon? What have I missed?
