Faaaaaaaaaaaaaar out!!!
2 March 2002 | by (Hong Kong) – See all my reviews

"Godzilla vs. Hedorah" is probably my favorite Godzilla from the 1970s (the others being the one with Gigan in them, he RULES TOO!). There sure is alot going on in this crazy movie.

There are:

ACID TRIPS! Strange anime sequences! Really upbeat soundtrack and theme song (KAAAAAAAAISEN!)! Kids in hot pants! Ecology made fun! Haiku! Nightclubs! Hippies galore! Godzilla flying! Hedorah, the strange looking beast of Smog!

This film has everything a B-movie enthuaist wants!

Even though a lot of people hated Hedorah, but I don't. He is one of the most interesting looking and powerful foes in Godzilla's old days. He pretty much hacks up on Godzilla a lot, changes shape at will, plus, it FARTS out acid!

Anyways, watch "Godzilla vs. Hedorah"! You'll have a B-movie blast!
