If i'm not mistaken, the water suit is the same old water suit from Biollante, only MUCH worse for wear.... It's pretty much falling apart at this point.
Despite all its flaws (& there SO many!), I actually like this movie. It's sort of a guitly pleasure I guess. It's got (imo) the best 90's Godzilla suit that really "cemented" the look of the Heisei Godzilla. It's also got some fun spfx sequences. Even though they are total ripoffs of scenes from better movies, they're still fun to watch. This was also the last heisei movie I ever saw, so it kind of held a slight "grail" status as it was the hardest for me to track down. It's bad - i mean, really bad - but it's still fun to watch in a "Plan 9" sort of way for me, unlike something like Spacegodzilla that I just canNOT sit through no matter how hard I try.
