I wish I had seen this trailer when it originally aired in my area- I had no idea it was a Godzilla movie and figured I could take a chance on not seeing it then. I learned the next day at school I had made a large error, since all my friends were talking about it. I think I had to wait at least a year before it aired on Channel 2 again.
I do still think the title Monster Zero is one of the coolest movie names. It's a nice break from all the "VS" movies Godzilla would later star in, I must say. It's also quite mysterious- I actually had no idea that Ghidorah was going to be Monster Zero until the movie aired. That won't ever happen in these days.
