The other night I rented Godzilla Against Mechagodzilla, which was a very interesting and surprising experience.

I'm going to start off with a bit of a geek history lesson to give some context to my story. For those of you who are not "in the know" (ie: most people), there were two distinct sets of Godzilla films. First there was the original classic, "Gojira" (1954), which started the whole phenomenon. It was followed by "Godzilla Rais Again" (1955) and then a number of sequels known as the
Showa series, concluding with "Terror of Mechagodzilla" (1975).
There was was then a ten year break before the aptly titled "The Return of Godzilla" (1985). This film ignored every sequel to the original "Gojira," and set itself up as a direct follow-up to the events of the first film. This began the
Heisei series of Godzilla films, which saw re-imaginings of many of the classic Godzilla villains, including Mechagodzilla in "Godzilla vs. Mechagodzilla II" (1993). The main difference between the two series was the attitude towards the monsters. In the Showa series they were treated as forces of nature, not evil beings, and Godzilla became something of a hero. In the Heisei series, on the other hand, Godzilla and his friends (or kaiju, aka monsters, your geek word of the day) were more often seen merely as hazards to human life.
Now, as far as I knew that was where the complexities of the Godzilla canon ended. Ignoring the American remake, as all good 'zilla fans do, there were simply the two series of Godzilla continuities. So, when I rented "Godzilla Against Mechagodzilla" I figured I was going to watch one of the three movies from the Showa and Heisei series in which the mechanical monster appeared.
How wrong I was.
