Dark Shadows is my favorite show ever made. I actually received another dvd set in the mail yesterday (I now own just under 400 episodes of the show). It's one of a kind. It is one of the very few horror based shows that didn't treat it's monsters as absolutes. Yes, Barnabus is a vampire. Yes, he kills people. But he hates himself for it.
To be honest, the Barnabus story line is one of my least favorites from the show. There is a woman who is the physical embodiment of the Phoenix. There is the antichrist story, the Lottery story, and even a whole story line done with a Cthulu cult. And this was all in the 60's.
However, Tim Burton is a hack, and he is going to ruin it.
I'll still go to see it.
