The 1958 movie contains examples of:
- Cult Classic
- Madonna–Whore Complex: A beautifully clear-cut example. Nancy is the madonna, while Honey is the whore.
- So Bad, It's Good
- Special Effects Failure: Boy, howdy! Both the giant alien and Nancy appear translucent and glowing in several shots, presumably due to bad compositing.
The 1993 remake contains examples of:
- The Woobie: The way Nancy is treated before she grows definitely sets her up for Woobie status.
