A safe haven for Borg?
4 March 2015 | by MartinHaferSee all my reviews

When the episode begins, Paris is re-instated as a lieutenant because of his nice behavior (if you remember, he previously lost his rank due to his completely disobeying Janeway's orders when they visited a water planet a season ago). However, the fun and games are, of course, only a prelude to bad things.

Soon the plot becomes all about a weird hidden safe haven for SOME Borg. In other words, some strange anomaly allows a small number of the drones to spend their recharging time in a happy haven (Unimatrix Zero) for folks to live out virtual lives as non-drones. Of course the Queen of the Hive isn't thrilled and is trying to locate all these drones and kill them. When Voyager finds out about this, the Captain wonders what they can do to facilitate the drones to not only live out their individual lives in the Unimatrix but extend this to their waking lives.

All in all, a very creative and cool episode--as are all the Borg shows. Well worth seeing and episode 2 in this series is even better.
