The evolution of the Heisei Godzilla films (1985-95) follows the same evolutionary path of the original series in miniature. GODZILLA 1985 was a serious sequel to the original GOJIRA, GODZILLA VS. BIOLLANTE was originally supposed to be a remake of the third film featuring Godzilla, KING KONG VS. GODZILLA, and by GODZILLA VS. KING GHIDORAH, the series plunged headlong into the mid-sixties "Yes, now we're just going totally nuts!" plotlines of GHIDORAH THE THREE-HEADED MONSTER and MONSTER ZERO. GODZILLA VS. SPACEGODZILLA, the sixth of the Heisei series, bears a strong resemblance to the modestly budgeted island-bound films of the later sixties like SON OF GODZILLA and GODZILLA VS. THE SEA MONSTER.
The premise of the film, however, is firmly in the "going totally nuts" category. Somehow, cells from Godzilla's body wind up in space, something that is blamed on both Biollante and Mothra, and those cells are mutated by radiation and return to Earth as Spacegodzilla, a Godzilla who has pointy crystals all over his body and several interesting powers Godzilla lacks, such as being able to generate a force field around himself. The reason for his return is left vague, but he seems to want to kill Godzilla, lock up his son Baby in some ice crystals and then make himself an an ice crystal Fortress of Godzillatude smack in the middle of a Japanese metropolis. Meanwhile, the Japanese have come up with yet another Giant Robot Monster guaranteed to fail at destroying Godzilla or any other Giant Monster. Needless to say, the two Godzillas and the Giant Robot Monster all wind up battling in a Japanese city, this time Fukuoka, causing the usual major damage to the country's infrastucture.
GODZILLA VS. SPACEGODZILLA is a fun film, but it goes on a bit too long for its flimsy story. Spacegodzilla's motives are never clear (why does he lock up Baby Godzilla, and for that matter, how does Baby Godzilla get out?), and we are denied a final tender scene of Godzilla meeting up again with Baby again, a moment the film feels like it is leading up to. The special effects are sometimes above-average, but occassionally fall to the level you might find during the host segments of your average episode of Mystery Science Theater 3000.
Still, the monster action is good enough to make the film a good, goofy addition to the series. - JB
