Did You Know?


The belt which Odo wore for the first six episodes of this season disappears in this episode. Rene Auberjonois had originally asked for the belt because he liked the look of the belt which costume designer Robert Blackman had designed for the all-black outfit in "Crossover". However, on the beige costume, Auberjonois felt that the belt looked "Buck Rogers-y" and asked if he could remove it. Kira finally notices the difference in "Crossfire". See more »

A neat idea but it did seem to take a LONG time to get to the finale...
21 December 2014 | by (Bradenton, Florida) – See all my reviews

While doing some routine work on the station, a long-hidden program is activated. It seems that an old Cardassian program designed to handle rebellions by Bajoran slaves on the station was hidden in the system and has just begun broadcasting warnings from Gul Dukat. The warnings indicate unless the rebellion is stopped immediately, stern measures will result. The stern measures mean a release of poison gas! So, as the Commander and crew try to turn off the program, they need to keep moving in order to prevent from being killed. Eventually, however, the real Dukat arrives and he thinks this is all very funny. Well, by the end, the joke is on him. See this one and see what I mean.

The idea for this show is pretty novel and generally good. However, it is hard to sustain this for the entire program and eventually it becomes a bit overlong. An excellent idea but one that was difficult to sustain for so long.
