Cardassia joins the Dominion, and the battle comes to Deep Space 9.
That big fleet turns out to be mainly interested in helping out Cardassia, and so the attack on DS9 is left to what is, really, a James Bond supervillain plot. It felt like a weak use of the Changeling-Bashir.
The best stuff is the escape from the Dominion prison, which appears to be a conscious homage to The Great Escape. And the new setup for the series is promising, finally bringing the Dominion threat much more clearly into the Alpha quadrant.
460 down, 277 to go.
