I've been trying to avoid learning any more information before I actually see the film, but I've just watched the trailer anyway. I don't think there is really anything new in it; Depp said a long time ago they were going to play up how Barnabas adapts to life in the 70's, and they've been using the word comedy to describe it for years; people just didn't want to beleive it. I thought two of the jokes were really amusing; regarding Barnabas being 'stoned' and Elizabeth informing him they don't have horses. Even that scene where Angelique rips open her blouse or w/e was fun, and sort of reminded me of a scene in Eating Out 3... But it is a very typical trailer in that jokes and humurous, light moments are edited and emphasized in ways that don't really reflect the resulting film (for instance, it seems obvious to me that they edited in the phrase "I'm a vampire.") I thought it was interesting how Angelique in the 1700's had dark hair, and then blonde in the present; sort of a reverse Cassandra.
I don't really hate the trailer, I wasn't that shocked by it and I still want to see the film. What has always interested me was seeing what they did with the material, how they interpret, adapt, and comment on it. If they didn't make any interesting changes or choices then it would just be another 1991/HODS retread, which I would rather boil my eyes than sit through.
Personally it is my feeling that the original series was on the air long after it's prime, and storylines such as the Summer of 1970 and 1840 were really bad, campy, and cheesy at times. I imagine a trailer could be made emphasizing things like Pansy Faye's dance in the 1897 old house, Prof. Stokes walking down the stairway through time surrounded by psychedelic flashing colors, Quentin and Desmond's "jailbreak" in 1840, etc. that would make it seem like the original series was also never serious.
