The first film in Daiei's "let's ripoff Toho's Godzilla series" to feature the giant super turtle is your typical Kaiju cheesefest. Full of the toy like special effects and noisy city smashing one has come to expect from these bargain basement monster flicks. Additional U.S. footage featuring Albert Dekker is hilariously bad. Gammera would go on to battle some of the goofiest monsters in Kaiju history in following efforts.
