This is one of the very worst of Japanese kaiju films (and that's saying a lot). Luckily, though, it definitely falls into the "so bad it's fun" category. Guiron is a hilarious monster, and his fights with Gaos and Gamera are so cheaply staged that you can't help but smile. The dubbing, too, is possibly the poorest you'll ever see. Two points of irritation: the obnoxious cop Kon-chan, who serves no point whatsoever (of course, neither does the film as a whole); and the song played while Gamera is flying through space. I guarantee, once you hear that song, you will never, ever get it out of your head. Beware!
