Godzilla Against Mechagodzilla (2002)
What it's really about: Overcoming your loneliness
When Godzilla finally shows up: Godzilla rides a Typhoon at the start, but that's a tease for his spotlight moment 37-and-a-half-minutes in.
Human plot: 6 - This time, Mechagodzilla is made from the bones of the original 1954 Godzilla, which give it DNA memory. The female loner pilot of "Kiryu" (they give Mechagodzilla a name in this one) must learn to conquer her own demons and work with the machine to battle Godzilla. So, yes, the plot of Pacific Rim.
Monster action: 7 - With the benefits of modern CGI and green screen techniques, the Godzilla-Kiryu throwdown is kicked up a notch from how these characters usually battle one another.
Camp factor: 4 - There are heartfelt moments where a little girl insists Kiryu has a soul and that the soul is tired of fighting. It's hard to tell if it's supposed to be taken lightheartedly, seeing as the main character is emotionless.
Ghidorah, the Three-Headed Monster (1965)
What it's really about: Add more monsters to the blueprints
When Godzilla finally shows up: 39 minutes in, after we've already seen one of the Mothra larvae and Rodan, the pteranodon who crossed over from his own series.
Human plot: 4 - Not only are the Mothra fairies on a publicity tour, I guess, but there's also a priestess who is possessed by an alien and a lot of hullabaloo over a meteor that ends up containing King Ghidorah, the space hydra.
Monster action: 7 - Even though it takes awhile to get started, this giant monster battle has all the hallmarks of a good Showa battle, dropping in monsters like a kid with a toy box.
Camp factor: 8 - A Mothra larvae shows up to talk to Godzilla and Rodan -- i.e., a 10 minute scene of the Mothra fairies translate what the monsters say while the suit actors flop around like muppets.
