* MagnificentBastard - Sandoval has his ways with charm and redeeming qualities and in the end might be the TragicHero.
* ParanoiaFuel - the whole freakin' show.
* TearJerker - [[spoiler: Boone's death at the end of the first season]]
** Todd's death in the next to last ep.
* SpecialEffectsFailure / VisualEffectsOfAwesome: Some of the effects have aged very well, others not so much. Amusingly, the mothership in Season 1 was awful even for the time, while it's updated look from Season 2 onwards is probably the show's best effect and holds up well today.
