This is Sci-Fi about alternate universes created with every life choice we make. What if we had made a different choice? There's a universe for that choice.
This series was made in Barcelona, Spain and as such uses the Catalonia dialect of Spanish. Since I don't speak Spanish I tried different ways of viewing the series. I personally prefer the English overdub without subtitles, but every option is available. You could listen to the original Catalan Spanish with English subtitles, but I find the subtitles inaccurate. In any case, this series is absolutely excellent for any Sci-Fi fans who happen to also be hopeless romantics.
