||Dark Frontier is an overall enjoyable Voyager episode. We learn a lot about the Borg and the episode is just in general a thriller. While I try not to nitpick some continuity issues in this episode really stand out, even to casual fans. The most irritating for me is the Borg Queen's statement that Seven is the ONLY Borg to escape the Collective. Even casual fans know this not to be true, because most of them have seen TNG's The Best of Both Worlds which directly dealt with Picard's assimilation, and his eventual escape. It doesn't matter whether Picard was a drone for only six days or not, he WAS a Borg drone that escaped the Collective, so therefore Seven is not the only one to do this. How the Voyager writers overlooked this is simply astonishing, considering a lot of them worked on TNG, and if that wasn't enough there was even a movie that dealt with Picard's need for revenge against the Borg for what they had done to him! It may be only a small statement in the episode, but it is a pretty big screw up, enough for me to drop a point for the overall episode. Fortunately the continuity issue aside the episode does a great job giving us 90 minutes of pure excitement and dealing with Seven's own demons with the Collective. 4/5 (Minus 1 for the continuity screw up ranted about above).
