Critic Reviews from Rotten Tomatoes

"A sense of humor is required to appreciate this slice of goofy, cheesy late 'Sixties sci-fi!"

‑ Dennis Schwartz, Ozus' World Movie Reviews

‑ Lucius Gore, ESplatter
"A stunningly cheesy old sci-fi corn-fest."
‑ Scott Weinberg,

‑ Jeffrey M. Anderson, Combustible Celluloid
"Japanese horror junk featuring American actors."
‑ Steve Crum, Kansas City Kansan
