Godzilla's masterpiece is the original Japanese version of the original movie. Gojira. That movie is a powerful piece of cinema history and I think is one of the most effective pieces of cinema ever made about the aftermath of Hiroshima. They just happen to disguise all the stuff about nuclear bombs in a monster movie. No Godzilla movie has even come close to it, but it is hard to. Gojira was made to be a statement on Hiroshima in a time when Japan was still reading from its devastation. Since Godzilla has become a more commercial icon, the series doesn't reach for that type of depth. Which is fine. Godzilla's identity has evolved over time and I love Godzilla films. Even bad ones. They're just fun times. KOTM was a stupid movie, but I loved it. But as a film enthusiast, I also have to call em as I see them. Gojira for me is the best Kaiju monster movie ever. I don't think it has any real contenders.
