This is a terrific program, and all of the seasons should be released on DVD, including the pilot. Craig T. Nelson, does some really good acting. You really get involved with the storyline, and also, the lives of the characters. The direction is extremely good as is the casting. Written by the man , who, lived it, (with another author) makes all the difference. The stories are much more believable, than most of the police shows, that are being broadcast, at the moment. This program, has a good moral basis. It shows that, even faced with insurmountable odds, if you are determined to make a difference, in the world, you really, can make a difference. Please start releasing the seasons. Thanks.
