- Evil Is Sexy: Livia. Oh, Livia. Amusingly, Pendragon seems thoroughly immune to her charms.
- Heartwarming Moments:
- Diane being inspired by Helene's sacrifice.
- Helene telling Meg that while she was creeped out by her at first, she now loves her like a family member.
- Hilarious in Hindsight: Quintus uses hypnosis as an Animus!
- Idiot Plot: Quintis's temporal tomfoolery aside, most of the plot is moved by the fact that Pendragon is dumber than a sack of concussed doorknobs.
- Narm: STAY!
- Narm Charm: The crew on the Satellite of Love had a lot to work with, but looking past the admitted cheesiness, there's actually some pretty solid acting, decent dialogue, and an interesting plot. A higher budget might have been enough to push it into the ranks of Corman's more respected films.
- Prop Recycling: The bats that Livia and her imp change into are recycled props from Corman's It Conquered the World.
- So Bad, It's Good: Everyone involved is clearly trying. The surprisingly decent-looking sets also deserve special mention, considering the whole film was made in six days in a converted supermarket.
- Squick: Satan's apparently off-centre Adam's apple.
- Tearjerker: Helen's decision, even though she's innocent.
- Too Dumb to Live: Scroop knows Livia is an evil witch, and just acts as if he's immune from her plans.
- Values Dissonance: Pendragon tells Helene that "[She] couldn't fool a child in its cradle" when she claims to have deceived Meg Maud. It's meant as a compliment to her guilelessness and purity of character, but today it sounds like a straight-up insult.
- Vindicated by Cable: Despite the meager budget, The Undead is one of the more thought-provoking B-movies of its kind.
YMMV / The Undead
