Admittedly, the English-dubbed version I watched may not have done the film justice, but "Gamera vs. Zigra" is pretty awful, even by bargain-basement kaiju-eiga standards. Briefly, an alien spaceship attacks a moonbase, then plunges into the ocean near Japan, from where Zigra kidnaps two kids and their fathers. There is a lengthy expositional scene where an alien space-babe (with '"super-celestial powers"), who seems to be channeling some kind of giant space-shark, explains Zigra's backstory, informs us that resistance is futile, and demonstrates diverse abilities such as causing earthquakes and hypnotising subjects with a snap of her finger. Typical of the Showa-era Gamera series, grownups are ineffectual, but the children manage to rescue their stupefied fathers and escape. Gamera attacks the submerged spaceship, which inexplicably changes into a monster resembling a gigantic, robotic 'goblin shark'. Various adventures and battles follow, with the two children always in the thick of things. As usual, Earth's puny weapons are proven useless and only Gamera, the children's friend, can save us. At times, the film (or at least the dubbed dialogue) makes no sense: explaining Zigra's origins, the space-babe states "We on Zigra planet, we used to live in the sea but your Earth science polluted the water and we could no longer live there", this despite the fact that Zigra is 400 light-years from Earth. The special effects are low-budget and not very effective, with most of the monster action underwater or on a beach. The Gamera suit looks as unconvincing as ever and the silly Zigra costume is on par with most of Gamera's goofy kaiju foes (Gyaos being an exception). In keeping with the drift toward 'environmental values' in the genre ('Godzilla vs the Smog Monster' was released the same year), the film has lots of preachy moments about valuing the oceans, etc., yet opens with what is essentially a plug for "Sea World". There are also several references to Coke, the tiresome little girl's libation of choice. For a kaiju film, there is not a lot of 'action' and far too much time is spent on the space-babe's pursuit of the annoying children, descriptions of carnage and destruction that we don't get to see, and Zigra's continual gloating about his superiority, our dismal fate, etc. His comeuppance for this verbose posturing is to have his dorsal fins played like a xylophone by the triumphant turtle, who then breaks into dance (even sillier than Godzilla's infamous victory jig in 1964's 'Invasion of Astro-Monster'). Incongruously, after this lighthearted song-and-dance moment, Zigra is incinerated while still alive. The Gamera formula was getting pretty tired by 1971 and, perhaps fortunately, this was the last of the original Showa-era films. Other than 'starring' in 1980's dire "Gamera Super Monster" a compilation of fight scenes frame-worked by a ridiculous (and possibly imaginary) story involving 'space women', the giant, jet-powered, flying turtle hibernates until 1995's excellent "Gamera: Guardian of the Universe". One bonus: the score includes the 'Gamera Song', this time with lyrics and sung by a children's choir. If this memorably cheerful ditty doesn't lay an egg in your inner ear, nothing will.
