- Special Effects Failure: There's a moment in Part 4 when an Inter Minorian's bald cap completely slips loose. This was considered so bad by an editor that for some transmissions, the whole ending scene got cut out of rebroadcasts.
- The Drashigs are excellent monsters...when they're on film. They are considerably let down by the videotape work and CSO in the fourth episode.
- Values Resonance: Vorg and Shina getting stuck in a nightmarish airport security line due to xenophobia and ending up scapegoated as terrorists in a political coup works a lot better in the post-War on Terror era of zealous airport security and refugees being blamed for terrorist attacks.
