I was absolutely riveted to my TV as a teenager to watch this show. The settings were totally realistic, the acting was first rate with many excellent ny actors (Pacino, Clayburgh, Martin Sheen) as stars. It didn't hurt that I had a huge crush on Frank Converse as well. The stories were excellent and felt very true to life although that was way before I moved East. I was very upset when the show was canceled. The only other police series that I believe measure up are Naked City and Homicide, Life on the Streets.
