I would agree with Paul Andrews--early in the "Quincy" series the show was much more oriented towards solving crimes and as the show progressed, it became much more of a soap box for social issues. While the issues might have been quite laudable (such as sudden infant death syndrome in this particular show), the program became less and less entertaining as well. And, often the show was simply preachy.
Tyne Daley and Robert Ginty star as two parents who sadly have to deal with one of their twins dying from SIDS. While this is a serious tragedy, an even greater pain is inflicted on them when a complete jerk-face of a coroner incorrectly diagnoses the child as having died as a result of child abuse! So, Monahan is brought into the case and when Quincy finds out about this rush to judgment, he is naturally furious! The end result of this is that the parents are really screwed up and the young coroner has lost his nerve. Can they all overcome this? Not a terrible idea for a story but as I said above, this was NOT entertaining. A bit of light humor or tension would have made this one better. Instead, it's heavy-handed and anything but entertaining.
