I thought this was one of the better private dick programs. Rockford was a realistic guy, making statements like: "I'm not going in there, I could get KILLED!" Wise guys like Bogart would have bravely gone in and cleaned house, and looked corny doing it. Issac Hayes wasn't listed as a player, but was on enough to have been - if memory serves he did become a regular for awhile. Hayes added a nice touch to the show with his tough image and his reference to Rockford as "Rockfish", which drove Rockford nuts. Don't miss Stuart Margolin as the sleazy "Angel", one of his better parts.
