Pros:
Music is great, the animation in most parts is beautiful, the build up to Ghidorah is terrifying, the concept of worshipping Ghidorah as an almighty god is awesome and scary, and of course the metaphors behind this was thoughtful although.....
Cons:
... The execution was terrible. The writing makes no sense for motivation, reasoning and the events that take place. The ending is what made me hate it. It’s too fast, has an unsatisfying conclusion, Haruo’s death makes no sense and has little pay off. Haruo does not change and is a weak, flat character. He’s also a hypocrite and changes character in the first part of the movie in the wrong ways. Right after the second film, his girlfriend/love interest gets infected and is close to death, BUT despite that, it still doesn’t stop him from having sex with one of the twin fairies.
The animation was also lazy half the time, with flat smoke effects that look unrendered/unfinished. Half the time I thought I was looking at stock animation footage.
Godzilla’s still an object and barely moves in any way, shape, or form. Haruo’s hatred for Godzilla is flat out stupid. Despite a world ending monster coming to earth, on the verge of killing EVERYTHING AND EVERYONE, he STILL hates Godzilla. Even after saving Earth and himself. That’s where his change in his arc should have happend, realizing there’s more than just Godzilla and his hatred is not worth it. Kinda there when he kills himself, but its executed in a way not many people will realize it.
Mothra also makes a useless cameo, other than to save Haruo from a dream sequence. She does nothing else, and does very little sadly. Would’ve been more interesting to have her save Godzilla from Ghidorah as another god-like monster, but no.
Not a good way to conclude a trilogy, and a terrible one at that. Writing and direction is the weakest.
Grade: D+
