You know a franchise is popular when you get two films in the same year. This is the first film that decides to go when no monster franchise has ever gone before and put space into the story. The film sees Godzilla having to join forces with Mothra and Rodan to take on King Ghidorah. King Ghidorah is quite quickly built up to be the biggest threat Earth has faced and only by coming together can Godzilla, Mothra and Rodan defeat King Ghidorah.
The human stuff I didn't really find very interesting. It is perhaps the weakest that the human side of the story has been and because it wasn't as good it meant that it felt way too long before the film really got going and Godzilla got to do him thing. It isn't until the final 20 minutes or so that we get the big fight and I thought that this was a rare of example of having a longer.
I did like the fact that Godzilla was unwilling to work with Rodan and Mothra. What does slightly undermine it is that the humans just become commentators about what is happening between the three of them. It's helpful for the viewer but it's just not done with any creativity. Thankfully as the fight progresses then it covers up the human stuff and it worked out quite well in the end.
From a technical standpoint, the film is a bit mixed. The fact that the film had to be rushed into production does show because the Godzilla costume looks a bit more flimsy when it's moving but at least looks like Godzilla should. I thought that when Rodan was in the air he sounded like one of the Thunderbirds. The sound was very similar and it wouldn't surprise me if it was the same. In the air, Rodan looks really good, then the camera is close up on the creature and it has to fight then it doesn't look quite as good. I thought that King Ghidorah was a good puppet, it moved in a way which make it look more than just a puppet and it was nice to have something that was a proper threat which is the first time that has happened since the first Godzilla film. The main issue is an issue of the time, the fight sequences don't look particularly good. I know they were limited by what they could do in 1964 but its still an issue.
It's at this stage of the franchise that it occurs to me that if this were real then people would have stopped building houses and offices because it would be like 'whats the point?'. Whenever you see Tokyo you see no sign of the destruction that Godzilla and others have caused and yes its possible they tidied it up but by the fifth film, the residents of Tokyo (and most places) would question the logic of rebuilding.
Despite some issues with the film, I thought it was another improvement on the low that was King Kong vs. Godzilla. I thought that there were one too many elements which didn't work and reduced Godzilla further so he is only one quarter of the main characters. It is definitely worth watching just for Ghirdorah but if you a wanting to see lots of Godzilla then this isn't the film for you.
