My Love/Hate Complex with "The Nurses"
I can still remember seeing this episode for the very first time as a teenager over 20 years ago, and it left quite an impact on me for Margaret's (in)famous "lousy cup of coffee" scene. It was one of the first times we ever really saw Margaret have any sort of an emotional breakdown (that wasn't played for laughs because she was drunk, or having some sort of a rift with Frank), and showed us her vulnerable side that was, at that point in the series, an incredibly rare sight. I can even remember what my initial reaction was after seeing that scene for the very first time: "Wow! Margaret has feelings?!" That, for me, made this a particularly stand-out episode of M*A*S*H that I thought was one of its best offerings.
At first.
After I repeat viewings of the episode over the years, that opinion has gradually shifted to the point that I now really don't even like this episode at all, and feel it's one of the weaker ones. Not at all because of Margaret whatsoever, but because I feel like this episode suffers from the same sort of problem that made another episode like "Edwina" a decidely weak installment as well, and that's the main cast of characters are more-or-less reduced to supporting characters, while the guest characters (almost all of whom we've never seen before, and never even see again) are the ones who carry the story. It makes the episode feel less like an actual episode of the show, and more like an entry from an anthology series. Like Edwina Ferguson, it's difficult to swallow that the writers expected us to really invest in the foibles of characters we've never met before, know nothing about, and then never see again without setting up that they could at least be minor recurring characters. One of the nurses (Gaynor) is even implied to have been at the 4077th for so long that she's become numb and desensitized to all of the casualities she's seen die in the hospital (including one who apparently had been flirting with her for a while). If she really had been at the 4077th for a while, and we saw over the course of multiple episodes the emotional toll all of these deaths took on her, maybe it would make her plot thread would have a better connection with us as an audience, but for a one-shot character, it seems too much to expect of us.
At least other similar episodes like "George" were executed a little better: George's homosexuality drove the plot of the episode, but he himself wasn't shoved into the spotlight and expected to carry the weight of the story himself - instead, we see how the revelation of his homosexuality affects the 4077th personnel, from Frank writing a formal complaint to have George dishonorably discharged (while Margaret backs him up), to Hawkeye and Trapper trying to stop him from ruining a good soldier's life, to even Henry not giving a rat's ass either way because of course he doesn't want to get involved. Even in "The Nurses," there is tension between said nurses and Margaret always breathing down their necks, but again, it's these random, expendable nurses who carry the show, while Margaret just pops in to yell at them and order them around, then we see her have her big emotional breakdown because of how they treat her. Not very effective.
Of course, that's just my opinion anyway.
M*A*S*H isn't the only show this has ever happened to of course. I remember THE ODD COUPLE doing something similar once with an episode about a couple of droopy kids who couldn't make up their minds whether or not they wanted to get married - we never see this couple before, we never see them again, but apparently Felix was asked to be best man at the wedding and he ruined it, so he and Oscar had to try to get the couple back together. Just the same, Felix and Oscar are reduced to supporting roles, while we're supposed to invest in this awkward love story between this young couple we know nothing about.
