I thought that both George Segal and Maggie Han did a great job with unorthodox characters. Who ever heard of an ex-alcoholic insurance investigator living with a extremely beautiful Asian model? Their living situation was even more odd. The apartment they shared was basically one big room, so their respective areas were separated by a wool blanket hung from the ceiling. It was one of the few shows with an Asian character that wasn't terribly pigeonholed into a typical Asian stereotype. Her character was a breath of fresh air in the late 80's.
If you ever get a chance to catch it in reruns, I highly recommend watching it.
