this movie for the second time ever (since seeing it subbed on VHS about 16 years ago) and I don't think it's nearly as bad as many fans do.
sure, it's full of flaws and it's about 20 minutes too long- some judicious editing would help the movie a lot. that and some hand to hand fighting between the monsters would have been nice as well.
but just what the hell was Space Godzilla? it didn't seem that clear in the movie, though Wiki says it's a combo of Godzilla and Biollante and a black hole. bet it was the aliens from the third planet...
why did it want Little Godzilla?
