Acá les paso el comentario de BadMovies.org, en inglés:
Often billed as the worst movie ever made, and not entirely undeserving of the title, this is a masterpiece of Ed Wood's making. Bela Lugosi was cast in the role of "Ghoul Man" but passed away before filming really started. So what happens? The producer's wife's chiropractor (Mr. Reynold's was the executive producer) takes over as "Ghoul Man" and holds his cape in front of his face THE ENTIRE MOVIE. Add to this numerous plot inconsistencies, horrid acting, and masses of stock footage - some of which we see several times and you have a terrible but funny movie. A highly advanced alien culture is determined to destroy Earth before our scientists discover a bomb which will explode sunlight, the description Eros gives of this is quite funny. In order to destroy our world, of several billion people, they raise three zombies from the dead. I have to tell you that despite this film's horrid nature, I dearly love it for being so bad.
Vale mucho la pena verla, en especial si hacen como yo y antes se ven la película de la vida de Wood, Ed Wood, dirigida por Tim Burton.
