A rough flight...
The film somewhat presents itself as a faux documentary, as a mean of narrative during its first scenes. From then on, it never drops its military vibe. Indeed, Rodan is a beautiful metaphor for something much worst, namely the hydrogen and atomic bombs. It works well without its message, although we wonder why the army plays such a heavy role and why the protagonists are written to be so cold.
Godzilla and Godzilla Raids Again came out two years before this. As a kaiju film, it isn't as tense and shocking as its predecessors and shows hints of something more ingeniously fun rather than dark and grieving, as was previously the case. The monsters are visually interesting. What they lack in design and credibility they still gain through clever photography and style.
Anyone who wants to see a city destroyed by a mutated pterosaur that's, in return, bombarded by jets and tanks will be thankful this movie exists. Sure, the building models and the beasts sometimes look lame, but this never stops the writers from pulling their crazy stunts. It gets away with a lot by masking its forgivable mistakes with smoke, dust particles and other mystifying camera tricks.
