It wasn't a direct remake of the 5 year/5 day a week show but rather loosely based on the story. It was exactly what one has come to expect from Tim Burton. Johnny Depp did an amazing portrayal of Barnabas Collins. I loved it, and as soon as it's on DVD, I will get it and watch it again. :)
I think if a person likes or hates it will depend on what they were expecting. If it is viewed by someone expecting the movie to capture the true essence of the Dark Shadows series, it would be a let down. It is, after all, directed by Tim Burton! I think, having recently watched the full TV show from start to finish, was a plus for us. We knew what was different and what was the same. We also went knowing it was a comedy and somewhat of a spoof off of the TV series.
