I noticed that the other reviewer hated this episode and called it horrible. While I love the reviews by Mr. Andrews and think they are often better than mine for this show, in this case we just seem to disagree. While I do think the episode has problems (which I'll talk about below), overall it is decent.
The show suffers from two major problems. First, there really isn't much Quincy in the show. Second, there really is no crime to investigate. Normally, these would be the kiss of death for the episode and I must admit that "The Flight of the Nightingale" is weak in these ways. The best shows in the series were clearly the earlier ones--where REAL crimes were investigated.
Despite this, the show does point out a serious problem--the lack of respect professional nurses get from doctors. While I assume this improved since 1981, when I worked in a psychiatric hospital in the 80s, I could see this. In the case shown in this episode, a doctor screws up and blame is assigned to a nurse--and the nurses end up going on strike to get better pay and more respect. Actually, now that I think about it...this show was pretty weak as it had a higher than normal amount of speechifying and seemed a bit preachy. So, you have a serious legitimate problem that is addressed in a less than stellar manner. I say three cheers for nurses, only a minor single hooray for "Quincy"!
