Godzilla 2000 is the Stereotypical Godzilla film. by which I mean, it sums up the entire franchise as a whole and does a damn good job at it.
It combines all 3 characteristics of all 3 series and can be fit into any of each's continuity.
What I find interesting abut it is how striking it looks compared to the other Millenium Godzilla films. It looks older than it is, in the way its shot and on what film they used. It's brilliant.
Furthermore, people often mistake Final Wars as a throwback to the Showa era. They are wrong. Just because the monsters do stupid things and there's alot of them, doesn't make it more like a Showa film. If anything, Final Wars is a huge step back, rather than a step forward. Godzilla 2000 however matches the plot structure and visual style of a 60's Godzilla film to the T. It's perfect. Godzilla is also most similar in attitude to that Godzilla. Also in terms of music. Everything about that film is Showa. Godzilla 2000, like the Showa films, also wrks as a film you can jump right into. With the Heisei series, and all the Millenium films, they rely on back story and previous films' continuities. Godzilla 2000 doesn't need any exposition or previous viewing, much like a Showa film. It's just a straight forward, old fashioned, Godzilla film. It's a PERFECT throwback. One little thing I love, is like in the 70's films, you get that hyper close up shot of character's squinting to flashing light.
It's a perfect Godzilla film and it defines the entire franchise in a nutshell.
I only wish it was called Godzilla vs. Orga, like I call it, instead of Godzilla 2000, because 2000 dates it.
