The first film was just a retelling of the first year of the soap -- with a bigger budget for film. I didn't like they fact they killed off the cast though...that was dumb.
Yeah, and they pretty much made Barnabas an animal without a conscience, exactly what made him likeable in the soap.
The second one was a complete disaster in my opinion. They didn't do justice to any of the characters -- especially Angelique. It was ridiculous to make a movie about Angelique and not have Barnabas in it -- but, with the way they did House of Dark Shadows, I supposed they had little choice if they were determined to make a film with Angelique.
They didn't have many characters left to play with. I gather that there were some major cuts for time which hurt the story a lot.
I enjoyed the 90's version as well...and I agree Joanna Going had a lot "going" on...

But, typical of the big networks, it was never given a chance and was preempted quite often if I recall correctly...
Yeah, right about the time it started we got into Gulf War I so there were lots of breaks and pre-emptions.
The only character in the '90s remake that I didn't care for the portrayal was Lisette Anthony's Angelique. IMO, she just played Angelique as evil, without any redeeming characteristics...and she didn't have Lara Parker's entrancing laugh.
