- Even Better Sequel: To Ghidorah, the Three-Headed Monster. Ghidorah was already one of the better-regarded films of the Shōwa period, since it featured the series' first Kaiju team-up, it was the first entry to incorporate elements of Space Opera into its story, and it introduced the Breakout Villain King Ghidorah. This film takes all the things that fans loved about Ghidorah and polishes them to a fine sheen: Godzilla and Rodan's fight choreography is smoother, the Space Opera elements are bigger and more ambitious, Ghidorah's puppetry effects are more refined, and the action unfolds on a truly epic interplanetary scale.
- Evil Is Sexy: The female Xiliens
- Narm: From the American dub, three words: "A happy moment".
- Narm Charm:
- Glen's cry of 'you sticking rats what did you do to her!?' should be really ineffective and narmy but Nick's acting makes it work.
- Godzilla jumping on Planet X to memetic levels.
- The spaceship effects and the Planet X set are both far from realistic, but they're so damn cool to look at—and so unabashedly escapist—that you can easily forgive it.
- Visual Effects of Awesome: Once again, the great Eiji Tsuburaya outdoes himself with the effects work on King Ghidorah, pulling off the flying scenes and the puppetry on three independently-moving heads so awesomely that you can easily forget that it's a guy in a rubber suit. It helps too that, unlike previous films, Tsuburaya had a bigger budget to work with thanks to US producer Henry G. Saperstein.
