One of only a handful of modern police dramas I have enjoyed, this series was produced by Steven Bochco, who is more well known for his work on a similar show in the 80s: Hill Street Blues. Unfortunately however, CBS was unable to find a niche for this one. The characters were wonderfully drawn, and the show was well written, but it suffered from poor ratings and was cancelled after a single season.
I only discovered it after having watched another show with Yancy Butler, who plays Officer Anne-Marie Kersey. I had the good fortune of being able to pick up the series very cheap (about $10) and I'm glad I did!
