It's not perfect, but the story interesting. I think most of us, anime freaks love those Dragon Ball Z style fights, the big eyes and repetitive, but complicated plots. The quality of the graphics reminded me of my grades: it goes up and down. One second it looks great, the other it looks like the work of an amateur. I hated the voices. The guy with the brown hair at the beginning talked like an italian hit-man.
PS: I think, Albert Einstein must be that old guy's (the one with the white spiky hair) great-great-great-great-great-great-grand-father.
