Same producers and vague general concept, but that's about it. Importantly, the "masters of horror" are directors, while the "masters of science fiction" are writers, and book writers, at that, not screenplay writers. Of course, that means that the stories are adapted by screenplay writers and not directly by the original authors (in most cases). And the directors that they have tend to be TV directors, not film directors, so there's probably going to be some smallness to the cinematography, which is too bad.

Still, the first episode was reasonably well produced. It would have been nice if they'd done something better with the credits titles.
