Never been a huge fan of Godzilla movies (other than the old 60's and 70's versions). I think the genre has been overdone and always so over the top that it's just silly nonsense to showcase special effects. This one is different. It's not your typical Hollywoood monster movie. It's a Japanese production that focuses as much on post-war reconstruction as it does Godzilla itself. As Americans, we really don't know much about what happened to Japan after the war. We dropped two bombs, they surrendered, that's about it. Most American's don't realize that we essentially destroyed every single significant city in Japan, especially Tokyo, before dropping the bombs. As a student of WWII I found the storylines of regular Japanese people picking up the pieces and trying to move on to be very compelling. And just when things start to come together and everyone is getting back on their feet, here comes Godzilla to destroy everything again!
It has your typical Japanese overacting and sometimes unintentionally comical dialogue, but the special effects more than make up for it. The scenes of total destruction are very well done, bordering on superb. It won an Academy Award for Best Visual Effects and was the first Godzilla movie ever nominated for an Academy Award.
It's definitely worth watching. I have no idea what "Minus One" means in the title, but it's a great monster movie with a solid human interest storyline.
