An alien monster hovers above Earth
and steals carbon-based minerals.
It's not even as fun as that.
Dogora's a space octopus
Monster isn't really what you'd call "in" the movie
Hope you didn't come here looking for cool Japanese monster movie stuff like rubber suit wrestling, model tanks getting melted, and ray-gun toting aliens in capes and leotards, 'cause there's none of that business in Dogora. The monster is sort of cool but all the movie does with it is show an occasional picture of the thing to remind us it's technically a kaiju flick. Movie's mostly a lame crime comedy about diamond thieves. Blah.
Skull-faced Eisei Amamoto is in it if that helps.
