- Narm: The Black Guardian's incredibly hammy Evil Laugh goes too far into cartoonish territory to take seriously (literally going "Nyeeeaheheheheh!). Notably, said laugh is deleted from the "special edition" on the DVD, with the scene instead just ending with the Guardian throwing Turlough to the deck.
- Special Effects Failure: There's the scene where Turlough gets rescued after throwing himself overboard. Cue yellowscreen background of a ship with Mark Strickson hanging from wires in front of it while a net is brought over to scoop him up. Fortunately, many of the bad special effects were fixed when a special remade version was released on DVD along with the original episode.
- Visual Effects of Awesome: The sailing ships in space.
