Errand of Mercy
Errand of Mercy (Memory Alpha; SD Video) is a fun little episode. War breaks out between the Federation and the until-now-unseen Klingon Empire. The flashpoint is a little planet in the disputed zone called Organia, and both sides send ships to try to hold it. But nothing goes right, and the Organians are none too happy to be in the middle of this violence.
This episode does a pretty good job of keeping you guessing as to what’s going on, while still meting out enough action and information to keep you interested. The mysterious Organians and their bizarre actions provide a backdrop, and the Klingon Military Governor a superb villain.
In fact, he’s so good that he deserves his own paragraph. This is the guy who defines what the Klingons are. He’s the first Klingon we see, and he makes them brusque but smart, fierce but not foolhardy, and calculating in the best way. He is in microcosm the Klingon Empire that becomes such a big component of the Trek universe; you can see him as the originator of the entire genre. He’s terribly well written and superbly played, even if his Fu Manchu mustache and olive makeup look a little ridiculous.
