And then of course there’s Captain Spaulding who’s the worst offender of these early MASH characters: a clearly up-and-coming young singer looking for some exposure, which is fine but MASH was the wrong show to put him on.
You can actually thank co-creator Larry Gelbart for that: he created the character of Captain Spaulding as an experimental character - in this case, a camp minstrel. I didn't mind the music he provided in "Rainbow Bridge," but other than that, I'll agree he was a pretty useless character in other episodes.
Snowthy (Master of All Things MASH), how did you feel about Donald Penobscot?
Ugh.
Well, I can understand Gene Reynolds's desire to develop Margaret's character by having her get engaged and married to a steady man in her life, and show that she had outgrown Frank (something Loretta Swit was all in favor for) . . . but I swear, that season where their engagement was an arc, she was so annoying as frog, acting like a love-sick high schooler over him, bringing him up in conversation just for the saking of blathering on about him.
And then, just a couple of seasons later, they get divorced (which Reynolds was not happy about, but he had already left the show by that point) since it turned out he was not only unfaithful, but was every bit a sneaky weasel as Frank. Personally, I can understand how and why Margaret was as upset as she was over this, but honestly, I also saw it as her receiving a taste of her own medicine: she was a homewrecker by fooling around with so many married men - not just Frank, but all of those generals, and other higher-ranking officers . . . in her case, the shoe was on the other foot, and this time it was her husband fooling around with other women behind her back. You can pick whichever analogy you want: "Karma is a female dog," or, "What goes around comes around."
But . . . as for Penobscot himself? Meh. Aside from Margaret's growth and development, he really didn't add much . . . and considering we only actually saw him twice - both times played by a different actor - it wasn't really enough to become totally invested in him as a character. Not to mention all of the previous descriptions of him before we saw him (stocky, unibrow, no neck) made him sound like one ugly dude, even though Margaret said he was very sexy.
