Wow, only *one* review for this fabulous episode? How can this be? This two-parter really is Star Trek: The Next Generation at its very best. I'm reluctant to say too much, lest I spoil anything for those who haven't see it yet. Exciting, engaging plot, some good characters, some good surprises. And it wraps up a bunch of loose threads.
As a two-parter, it is hard to review what is essentially half-an-episode. Fortunately, the second half is as strong as the first, making this, in my opinion, the very best of the cliff- hanger two-part episodes. Yes, even better than The Best Of Both Worlds.
My only complaint is that much of the spoken Klingon is gibberish. Yes, "naDev ghoS" is correct for "come here!" And "Gowron, Dajon, Dajon!" makes good sense: Gowron, you have captured it, you have captured it. But, for instance, the line about the son sharing in the honors or crimes of the father does not contain anything resembling the word for father (vav), son, (puqloD), honor (batlh), or crime (HeS).
