Godzilla is definitely the good guy in this one. A scientist and his Godzilla obscessed son discover that a strange new lifeform is thriving on the world's growing pollution and it will grow to enormous proportions and is heading straight to Japan (further proving a pet theory of mine...). Only Godzilla can save Japan from this new horror created by man's own folly. Inevitably The Big Green One and Hedorah (who looks like a living pile of shit) must fight. Major property destruction ensues. How can Godzilla defeat a creature made of sludge?
This movie boggled my mind. First it wanted to be a protest to pollution, then it wanted to be a horror movie, then it just went all silly as Japanese hippies sing "save the planet" all the while Hedorah goes about farting, belching, spitting, and shitting deadly sulfuric acid everywhere! Then it happens... the Big Guy uses his breath weapon to rocket up into the atmosphere and fly! Yes you heard it right Godzilla flies in this one. It must be seen to be believed!
