And I think having Demian Bichir star certainly helps too!
This actually looks quite intriguing, and i agree that both of the films were very good. The ending of the films' story left it wide open for it to be taken in any number of directions.
The only concern I have is that the central character is a 12-year-old vampire. That inherently limits the series to one--possibly two--seasons. But actually, I think that anyway I tend to prefer shorter series that have a beginning, middle, and end--or at least a series conclusion that is satisfying even if it doesn't END the story.
