This movie has very little to do with the Elizabeth Short (The Black Dahlia) murder. It's mostly about the police and their personal lives and relationships. There is only one interesting character, and she just has a bit part. I had to watch this movie in two parts because it was just so disjointed and boring that I couldn't watch it all at once.
Some reviews of this blu-ray claimed that it looked soft but it exceeded my expectations in both picture quality and sound. I'm happy to have upgraded from DVD.
