Mark does his best to provide Eleanor with the human blood she needs to stay alive, with the series exploring human frailty, strength and compassion through a horror and fantasy lens.
Ahead of the series's debut, Bichir spoke exclusively with RadioTimes.com, teasing that audiences can expect to be fully gripped at the end of each episode.
"You will get what you like as an audience because if you, like me, like series, you want to be trapped at the end of every episode and you want them to make you hungry for more," he said. "And that is precisely what we have done. And that's precisely what you will feel and hopefully if you like it as much as we do, then you will be back."
Asked if this meant that there were big cliffhangers at the end of each instalment, Bichir added: "That's what a TV series is all about. They have to have cliffhangers there, and we have so many great cliffhangers.
