This is definitely one of my favorites.
I saw this one at the theater in the 70's.
Hedorah is the scariest monster Toho has ever created. They out did themselves with that suit design.
Those big red eyes were really creepy. Especially the tadpole form as it plowed through the water. Coming at you.
Compared to the T.V. shows that aired back then. Like Isis, Shazzam, Wonderbug, Ultra Woman and Dyna girl,etc.
G vs. H really wasn't that much more psycaldelic than anything else created back at that time.
It was a pretty strange decade. But we thought things were just groovy.
