Watching the Making Of featurette for the movie gave me a lot of insight into just how this film was good.
In the Making Of, they described how many of their cast and crew were new to Godzilla movies, including the director, which is strange since this is considered one of the best films in the genre. I think the reason for that is that sometimes when newcomers come to something, they can bring a fresh and different way of looking at something, which worked for this film. Also, you can tell that they were innovative since they basically took relatively unimpressive sets and made them into amazing scenes, shot good shots with never before seen cameras of their own invention, and just used imagination to breathe life in the film. And, they did it while keeping style and art at the same time as form and function.
One of the most amazing things was that to create Godzilla walking out of a volcano (a timeless scene), they actually built a volcano. Well, one that was much smaller than your typical volcano, but nevertheless, it is nice to know that they put so much effort to make such a realistic and classic scene.
As for the movie itself, it was excellent and one of my favorite films of all time.
The special effects were phenomenal and were rarely matched across the Heisei series.Everything from Godzilla emerging from the volcano, to Biollante evaporating, to the storm, to the Super X 2's scenes were just...wow. For example, Biollante was particularly well rendered considering the fact that she took up to 20 people to operate. The coordination of the man in the suit, the people operating vines, and the 20 or so people operating the lattice-work like structure to make Biollante run was amazing considering how complicated the prop was. And Koichi Kawakita and Co. performed their most amazing work here. Not only were they good and creating special effects, but they also used them effectively. Consider Biollante's sap spray which looked like vomit in production and just invoked disgust was used with not too much but just enough added in special effects to change it to a power that was more surprising and awesome than gross.
The editing was also amazing considering there were so many scenes shot, and they managed to use expert analysis to narrow down which shots were the best. I also loved the music and, well, just about everything about the film. In particular, the acting, story, and characters were all pretty great. Miki was an interesting character who would gone on to play such a big role in the Heisei series and the Saradian Agent was one of the more cool and interesting characters in the franchise. Meanwhile, Dr. Shiragami was satisfyingly unsettling. From his emotionless face to his reclusive nature to his creepy stares, he really came off as someone who could make a kaiju willingly.
Last, but not least, the two true stars of the film were at the top of their game. Godzilla was at his one of his most powerful and imposing times. In my opinion, the suit was great and trumped most other suits save Burning Godzilla, Zombiezilla, Keizer Goji, '62, and of course '54. And I would put it among those suits. Also, he really radiated the power and royalty that represents Godzilla. Not just that, but he was also fairly smart and determined. For example, he either was stubborn enough to fire at the reflective mirror until it melted or he was intelligent enough to know that it would eventually melt; either way, it fits Godzilla.
But Godzilla was matched by his costar, the macabre and earthen Biollante. First of all, the idea of a plant monster is unique around all of cinema, especially at the time, except Little Shop of Horrors and Day of the Triffids. And Biollante was different from these other monsters. It ceases to amaze me just how much work was put into the big old plant (FYI: There were over 100 designs submitted for Biollante). The rose form, first of all had a tranquility and uniqueness that really fit the design and surprised me when I first saw it. But an even more unique and excellent design was the final form which was an excellent cross between Godzilla, Erika, and a rose design-wise. Not only that, but in 4 1/2 minutes (how long the final form was present), it managed to achieve some of the most spectacular crowning moments of awesome that the series has had. Biollante running: a harsh and surprising feature that deviates from what we would expect of a plant and was an achievement of special effects. Her emergence: a quaking and ominous scene that presented to us one of the most amazing kaiju yet. Her head getting blown open only for it to heal seconds later: an amazing feat of regeneration. The impalement of Godzilla: a brutal and unforeseen scene of coolness. And the most incredible of all: trying to eat Godzilla! Talk about wow.
Anyways, I loved this film and almost everything about it.
