GHIDORAH, THE THREE HEADED MONSTER (1964)
aka. Three Giant Monsters: Earth's Greatest Battle
Aside from introducing one of Godzilla's classic enemies, Ghidorah, The Three Headed Monster is held up alongside Mothra vs. Godzilla as one of the best kaiju movies of the Showa series. At the same time, it is decried by many adult Godzilla fans. You see, Ghidorah heralded a monumental and culture-shifting transformation that many Godzilla purists are still not happy about. For 30 years following Ghidorah, Godzilla would be firmly and unequivocally depicted not as monster but as a kid-friendly hero. And it all started right here.
