Dark Shadows
It was revived in 1991* and they did a wonderful job with it, but just as it premiered the first Gulf War broke out and the media was consumed with video game war coverage, so it kept getting moved around and preempted so often no one could follow it and it got canceled after one season without ever having a chance to build an audience.
Given the popularity of 'Twilight', I can't imagine why no one has snatched the DS franchise up yet, it's perfectly suited to that audience. Tho I notice the new 'Dracula' series on Fox is using the 'vampire seeking a blood serum to help control his addiction' storyline in the promos, which is a direct ripoff of 'Dark Shadows' that was already appropriated for 'Blade.'
I haven't seen the Tim Burton/Johnny Depp version, but I don't really want to. Having grown up with the original show, I realize that it may seem a bit dated and hokey today, due to it's low budget and rushed daily shooting schedule and the fact that it was live TV, but to those of us who loved it as kids, it was cool as hell to have a show on every day with vampires, ghosts, witches and werewolves in it and I'm rather insulted Burton turned it into a farcical comedy.
