Generally, I tire of the Klingons in the Star Trek canon. But here, three great ones who were betrayed decades previously, return to fulfill a blood oath they took decades previously. The interesting thing about this is that Curzon Dax was part of that oath Jadzia needs to join them. They fight her along the way. This is a neat little story with each of the Klingons having a distinct personality that shines through. Dax is conflicted about actually killing others but the "Albino" is such a despicable creature that it hard to restrain.
