In San Francisco, Harry Fox, Sr. (Jack Warden) is a streetwise private eye. His son Harrison Fox (John Rubinstein) is a straight-laced lawyer trying to have a respectable practice. Harrison is married to Cindy (Penny Peyser) with young son Josh. Despite his reluctance, Harrison keeps getting involved in cases with his father.
It may not be a big deal to some but I really like the peppy opening theme song. It may not be one of the icons but it's one of the better ones. As for the pairing, I like the chemistry and Jack Warden is great. If there is anything missing, it may be a third on the team. It is sometimes Cindy but her role as stay at home mom is limiting. I often wanted Harry to have a secretary. For one great episode, Carol Kane is that secretary. It's a little too much to hope for a great to take that role. Certainly, Cindy could have taken the job. It would also be a great way to connect Harrison with Harry's cases which is often an issue on the show. The cases would have to fall into both of their laps. It may help even more if father and son are forced to work out of the same office. They wouldn't have to do the story gymnastics to get both of them into the cases. The show could have lasted much longer but some jumping around the schedule in its second season accelerated its drop. It's two seasons and a movie.
