Query: Disappointed in quality of DVD.

I really like this story, but am disappointed in the quality of the DVD. The sound was bad and the entire movie was very dark. In some parts, the scenes were so dark, it was difficult to see the action. And in some scenes, the lighting faded almost to black and then it came back. All in all, the quality is very poor, especially at the beginning of the movie. Are all of the DVD's of this movie like this? I gave it two stars because of the poor quality.
