An evil female alien captures some kids (who are obsessed with having a Coke) from Japan under orders from an oversized shark monster named Zigra. You see on Zigra’s planet, “Creatures from the sea eat the creatures on the land”, and since they’ve run out of food on their planet, they want to eat Earthlings and they have a hankering for Japanese. Fortunately the giant turtle Gamera is there to save the day. By this time (like the Godzilla series before it) Gamera was a “friend to children” and had his own catchy theme song. It’s slightly better than average for a Gamera flick thanks to the ecological theme and an extremely goofy monster.
