After reading the lastest description of the supposed trailer, I came away with the following understanding: [spoiler]The entire 1970s family is aware that Barnabas is a vampire, and is perhaps even protecting him.[/spoiler]
Did anyone else get the same vibe? What a strange change to the original story. If true, then that explains why the family accepts Barnabas, despite his unusual "look." Until now, it seemed perposterous that they would accept someone who looked like that as a member of the family. I'm not happy about the explanation, but at least,\ we have one.
