Considering the source material ("The Captain's Log") was a mere chapter in Bram Stoker's 1897 novel, "Dracula", I think the movie did an exceptional job. We're all familiar with vampire lore, but the environment where this film takes place is not. And contrary to some small-minded reviews on this site (chocapic and lotusland) people of color existed, even back then! For true horror fans, seeing Javier Botet (REC films) was an extra boon. All in all, this was a well done film and one that I have watched several times.
Eight seasons. It is done. Finished. I think that this series makes the point that sometimes a good idea should end after two seasons. The premise began very well: a family view of the zombie apocalypse from the West Coast USA, L.A. being a great stage for what could have played out. But before you knew it, the show spiraled out of control, challenges and premises getting weirder and wilder until the show became shambles. What a shame.
